GENERAL INFORMATION
This manual contains directions for use that apply to a number of models. In order to simplify references to certain models, the follow-
ing designation system is used throughout the manual:
PM6681 stands for PM6681, PM6681R and PM6681R/676/AF
PM668 1 R stands for PM66 8 1 R and PM66 8 1 R/676/AF
The PM6681R/676/AF is a model supplied with the following features:
- PM6681R base model
- Prescaler PM9624 (2.7 GHz)
- Rackmount kit PM9622
- Reference output option PM9671B
Refer to the respective type nunibers in the Operators Manual for specifications and other infomiation not found in this manual.
New options and deviations from the original design are collectively treated in Chapter 9, Appendix. Below is a summary of the
changes:
Unit 1
The main printed-circuit board (Unit 1) has recently been redesigned due to obsolescence of a number of integrated circuits. Designa-
tions found in circuit descriptions, schematic diagrams and parts lists in the first eight chapters refer to the original design. The func-
tional descriptions are correct on the whole, if you make a few substitutions. Anew set of schematic diagrams and a new replacement
parts list are added in Chapter 9, Appendix.
- Instruments having serial numbers >784919 belong to the new generation.
- The model PM6681R/676/AF has only been produced with the new Unit 1 board, so the serial number is irrelevant.
Model PM6681R
The model PM6681R introduces an ultra-stable rubidium atomic clock reference.
Option PM9671B
Reference output unit offering six buffered 1 Vrms outputs with four different standard frequencies: 3x10 MHz, 1x5 MHz, 1 xl MDHz
and 1 X 0.1 MHz.
New OCXOs
The PM9691 has been redesigned, and a version with very high stability , the PM9692, has been introduced.

This Timer/Counter has been designed and tested in ac-
cordance with safety class 1 requirements for Electronic
Measuring Apparatus of lEC publication 1010-1, and CSA
C22.2 No.231, and has been supplied in a safe condition.
This manual contains information and warnings that should
be followed by the user and the service technician to ensu-
re safe operation and repair in order to keep the instru-
ment in a safe condition.
WARNING: The opening of covers or removal
of parts, except those to which access can
be gained by hand, is likely to expose live
parts and accessible terminals which can
cause death.
The instrument must be disconnected from all voltage sour-
ces before it is opened. Remember that the capacitors insi-
de the instrument retain their charge even if the instrument
has been disconnected from all voltage sources.
Grounding
This instrument is connected to ground via a sealed three-
core power cable, which must be plugged into socket out-
lets with protective ground contacts. No other method of
grounding is permitted for this instrument.
The ground symbol on the rear panel indicates where the
protective ground lead is connected inside the instrument.
Never remove or loosen this screw.
Disposal of Hazardous Materiais
WARNING: Disposal of lithium batteries requi-
res speciai attention. Do not expose the
batteries to heat or put them under extensi-
ve pressure. These measures may cause
the batteries to explode.
A lithium battery is used to power the non volatile RAM in
this instrument. Our world suffers from pollution, so don’t
throw batteries into your wastebasket. Return used batte-
ries to your supplier or to the Philips or Fluke organization
in your country.
Line Voltage
The Timer/Counter can be powered by any voltage be-
tween 90 and 265 Vac without any range switching. This
makes it suitable for all nominal line voltages between 100
and 240 V.
• Replacing Components in Primary
Circuits
Components that are important for the safety of this instru-
ment may only be replaced by components obtained from
your local Philips or Fluke organization. After exchange of
the primary circuits, perform the safety inspection and
tests, as described in Chapter 5, "Repair".

Performance
Check
General Information
WARNING: Before turning on the instrument,
ensure that it has been installed In accord-
ance with the Installation Instructions
outlined in Chapter 1 of the Operators Ma-
nual.
This performance procedure is intended to:
— Check the instrument’s specification.
— Be used for incoming inspection to determine the accept-
ability of newly purchased instruments and recently reca-
librated instruments.
— Check the necessity of re calibration after the specified
recalibration intervals.
NOTE: The procedure does not check every facet of the in-
strument’s calibration; rather, it is concerned primarily
with those parts of the instrument which are essential
for determining the function of the instrument
it is not necessary to remove the cover of the instrument to
perform this procedure.
If the test is started less than 20 minutes after turning on
the instrument, results may be out of specification, due to
insufficient warm-up time.

Reference Oscillators
X-tal oscillators are affected by a number of external condi-
tions like ambient temperature and supply voltage but also
by ageing. Therefore it is hard to give limits for the allowed
frequency deviation. The user himself must decide the li-
mits depending on his application, and recalibrate the oscii-
lator accordingiy. See the Preventive Maintenance chapter.

To check the accuracy of the oscillator you must have a ca-
librated reference signal that is at least five times as stable
as the oscillator that you are testing, see the following ta-
ble. If you use a non 10 MHz reference, you can use the
mathematics in PM 6681 to multiply the reading.
- Set the counter to default settings by pressing PRESET.
“ Connect the reference to input A

The PM 6681 Timer/Counter consists of three main units:
- Front unit
- Main board unit
- Rear panel unit
Several options can be added, these are:
- Prescalers (1.3 GHz PM 9621, 2.7 GHz PM 9624,
4.2 GHz PM 9625B, and 4.5 GHz PM 9625)
“ Oscillators (TCXO PM 9678B and oven oscillators’
PM 9690 and PM 9691)
- Rack mount adapter (PM 9622)
- Rear panel inputs (PM 9611/81)
The chassis of the counter consists of a front piece molded
in aluminum, an aluminum rear panel, and three aluminum
profiles that hold the front and rear panels together. This
unit can be slid into the aluminum cover of the instrument.
The front unit contains all functions needed for the user
communication. A flat cable connects the front unit to the
main board unit, and the molded front-piece screws onto
the two aluminum profiles.
Most functions, such as the following, are placed on the
main board:
- Input amplifiers with trigger level circuits
- Power supply
- Measurement logic
“ Microcomputer circuitry
- GPlB-bus
“ Analog output
“ External reference input
- External arming input
Some outputs, such as the TRIGGER LEVEL and PROBE
COMPENSATION VIEW outputs are directly mounted on
the main board.
The rear panel unit is an aluminum panel with a number of
mounted connectors. Most of the connectors are soldered
directly to the main board. The rear panel screws onto the
two aluminum profiles.

The front unit is made of a moided aluminum front. The
keypad is made of siiicon rubber with screened carbon
pads on a PC board that covers the total front. An LCD
and four LED’s are used as indicators. To show both the
measurement result and the state indicators of the instru-
ment setting a LCD is used. The LED’s shows standby, ga-
ting, and triggering channel A and B.
It has 160 segments that are multiplexed with a ratio of
2:1. Two cascade coupled LCD drivers (U201 and U202)
are used. A serial l^C bus connects the drivers to the p-
controller on the main board. R201 sets the clock frequen-
cy of the drivers to approximately 140 kHz. The VLCD pin
is connected to GND on the main board.
A back-light is provided with the LCD. This is an LED array
integrated to one component, it uses approximately 0.35 A
and dissipates approximately 1 .5 W.

Figure 4-22 Keyboard scanning.
The push buttons are connected in a matrix and the scan-
ning signals HO to H7 are coming from the main board. If a
button is pressed and HO to H7 is high, one of the output
signals VO to V7 will be high. VO to V7 are also connected
to an interrupt input, P0.7 on the jiL-controller U6 via the
AND gates U21 and U87. The LOCAL-PRESET button is
not part of the scanning, but connected directly to the AND
gates U21 and U87.
Three screws fix the front unit to the main board unit. A
40-pin flat cable electrical connects the front unit to the
main board.
4-4 Hardware Functional Description
Main Board
Input Amplifier A
input amplifiers A and B are two matched 300 MHz ampli-
fier circuits: Channei A and channel B.
Channels A and B are identical except the 100-kHz filter in
channel A, the switching circuitry for the separate/common
modes, the B-channel delay line, and event delay output.
The following description refers to channel A but is also va-
lid for channel B, (see Figure 4-4).
Four main stages makes the input amplifier: Input stage,
impedance converter stage, comparator stage and buffer
stage.
• Input Stage
The input stage contains:
- 50 ^2/1 Mf2 impedance selector
- 1X/1 OX attenuator
- AC/DC coupling
- Voltage limiter
50 Q/1 MQ impedance selector
Figure 4~3 Impedance selector, 1X/1 OX attenuator
and AC/DC coupling.
Relay K2A select 50 O or 1 M£2 impedance mode. 50 ^2 is
selected via resistors R135 to R146 if the relay switch is
closed. 1 UQ. is selected if the switch is open, (see
Figure 4-3). Depending on selected attenuation, the 1 MQ
input impedance is determined by different combination of
resistors. Resistor network R7, R8, R22 to R24, and R92
determents the 1X attenuation. Together with 1X resistors
R4 to R6 and R10 to R12 sets the impedance in 10X atte-
nuation. The input capacitance in parallel with 1 M^2 is 15
pF. Resistor R92 immediately after the selector serves
both as current limiter with the voltage limiter (see below)
and as impedance matching resistor. This resistor also im-
proves the V Standing Wave Ratio of the amplifier.
1X/10X attenuator
The IX attenuator consists of the resistive low frequency di-
vider, which reduces the input signal by a factor of 2.3. R7,
R8, R22 to R24, and R92 forms the attenuator, (see Figure
4-3). The variable capacitor C40 and the parasitic capaci-
tance forms the capacitive high frequency divider in paral-
lel with R22 to R24.
Variable capacitor C40 adjusts the capacitive attenuator to
the same attenuation as the resistive.
Resistors R4 to R6 and RIO to R12 forms the 10X atte-
nuator. The variable capacitor Cl and the resistors R10 to
R12 forms the capacitive divider. The parasitic capacitance
is in parallel with resistor RIO to R12.
C432 set the 10X input capacitance equal to the IX input
capacitance.
AC/DC coupling
Relay K4A select AC/DC - coupling. In AC coupling relay
K4A is open and the signal is fed through the AC capacitor
C5, (see Figure 4-3). In DC coupling the relay K4A is clo-
sed and the AC capacitor C5 is short-circuited. To protect
the relay contact the two resistors R20 and R21 serve as
current limiters.

Hardware Functional Description 4-5
Voltage limiter
Figure 4~5 Voltage limiter.
A voltage limiter that protects the impedance converter
against over voltage is placed between the AC/DC selector
and the impedance converter, (see Figure 4-5). It consists
of resistor R26, the diodes D18, D62, and D8 to clamp po-
sitive voltage. Resistor R25 plus the diodes D4, D5, and
D9 to clamp negative voltage. The clamp voltage is appro-
ximately 2.7 V at low frequency signals. At high frequency
the clamp voltage rises to approximately 3.0 V.
• Impedance Converter Stage
The analog signal from the input stage is fed to an ampli-
fier stage where split-band technique is used to get a good
frequency response over a wide range, (see Figure 4-6).
This means that the high frequency path of the signal is
fed via a high impedance AC-coupled FET transistor stage.
In parallel via a DC coupled feedback operational amplifier
stage, the low frequency path is fed. The low frequency
path handles frequencies up to approximately 5 kHz.
Through the FET, V1 gate the high frequency signal is fed.
The high impedance at the gate is converted to a low impe-
dance at the source. Common for both high frequency and
low frequency path the source is connects to the HF-transi-
stor V25.
To make the FET work well in its active region within the
whole dynamic range, the FET-drain is supplied with +12 V
via resistor R94.
Two resistors, R16 and R17 divides the low frequency si-
gnal before it is coupled to the input pin 2 of the operatio-
nal amplifier U1. Resistors R14 and R15 at U1 pin 6, cen-
ter the output swing, and capacitor C3 stabilizes the opera-
tional amplifier stage.
The iow frequency path goes via the operational amplifier,
the base and collector of the transistor V25. This point (col-
lector of V25) is the common point for the high and low fre-
quency paths of the input frequency.
Figure 4-6 Impedance converter.
4-6 Hardware Functional Description
A driver stage (V22), an output stage (V23), and a current
generator (V26), forms an amplifier with high output cur-
rent. This amplifier is used to get a linear output in the
100Q load resistor R101 over a swing of 2 V.
From the output of this second amplifier stage, the signal
goes back to the operational amplifier pin 3 via divider R27
to R29 and R167. Trim potentiometer R167 sets the gain
of the low frequency path equal to the high frequency gain,
(about 0.9). Capacitor C30 is connected to U1 pin 1 and 8
to achieve stable operation. The trim potentiometer R18 be-
tween pin 1 and 5 on U1 is used to adjust the offset volt-
age of the operational amplifier.
The channel A filter connected to the output of the second
amplifier stage is a 100 kHz LC-fiiter. It consists of coil LI,
and two capacitors, C29 and C41 in paraiiei. Two reiay-
contacts, K5A and K5B, controis the filter. The filter output
is connected to the input of the comparator stage.
The output of the ampiifier stage is aiso connected to the
rear panel via the ampiifier U95. By using this output cailed
"PROBE COMPENSATiON A" it is possibie to compensate
a probe connected to the counter. This voitage is aiso con-
nected to an analog input in the p-controiier. This makes it
possibie for the p-controiler to get a quick knowledge about
the input voltage.
Figure 4-8 Comparator and buffer stages.
A DC level in the range of approximateiy -2 V to +2 V are
generated by the trigger level circuits, which are described
later. This covers a dynamic range of 5 V since the input si-
gnal is divided by a factor of about 2.4 before it reaches
the comparator.
The counter is provided with fixed hysteresis, i.e., it is not
controllable via the front panei or GPiB.
• Buffer Stage
Before the signal is fed further into the ASiC OQ0502, U58
it has to be converted by the buffer stage, (see Figure 4-
8). The negative ECL logic levels ( ~ -0.9 V to — 1.7 V)
from U3 pins 2 and 3, are converted to a single-ended si-
gnal with positive ECL logic levels ( ~ 4.1 V to ~ 3.3 V).
The buffer is a differentiai ampiifier consisting of the two
transistors, V27 and V28 whose bases are fed different! aliy
from the two comparator outputs. Resistor R63 sets the
current in the stage. Resistors R66 and R67 serve as cur-
rent limiters to stabiiize the stage and the two collector resi-
stors R64 and R65.
• Common B via A
Figure 4-7 Common B via A.
The output signa! from V23/ V26 can also be fed to the B-
channel comparator, (see Figure 4-7). This is done in Com-
mon B via A mode. Reiay K9A and K9B connects the com-
parator inputs pin 7 (A) and 10 (B) in paraiiei. Simultane-
ously relay K9B disconnects the output signal from input B
to the B-channel comparator, in separate mode, the relays
connect the output signal from input B to B-channel compa-
rator input pin 10 (K9B), and disconnect the signal from in-
put A to the B-channel comparator pin 10 (K9A).
The resistors R101 and R118 set the impedance in the
comparator stage to 100 Q.
The comparator stage converts the anaiog signa! from the
impedance converter stage to a square wave, (see Figure
4-8). This circuit consists mainly of the high speed integra-
ted comparator U3 and a separate trigger ievel circuit con-
nected to the comparator at pin 8 via resistor R87.
Hardware Functional Description 4-7
Input Amplifier B
Input channel B is the same as input channel A with the fol-
lowing exceptions:
— The Common B via A switches, that connect the B-chan-
nel comparator to the input signal on channel A.
- The B-channel delay line.
- The B-channel has no iowpass filter.
— The B-channei has a special event-delay signal output to
OQ0504, U56.
• Delay Line
A line of approximately 65 cm is placed between the "B-
channel comparator output" pins 15 and 16 and the buffer
stage V33 and V4, (see Figure 4-9). This delay line is a
part of the circuit board, it should compensate for delays in
OQ0502, U58.
• Event Delay
Also for use in the arming function, the inverse output from
the buffer stage V4 of channel B is used, (see Figure 4-
10). This signal called EVENT-DELAY, is connected to the
OQ0504 circuit U56 via the transistor V12 and the 1C, U47
which works as a multiplexer.
The EVENT-DELAY signal is also used by the HOLD-OFF
logic when the input puises should be counted, (see Coun-
ter circuits on page 11).
VI 2 U56
Figure 4-10 Event delay.
Calibration Circuits
U93 and a delay line on the PCA generates a xx ns long
pulse, and feed it to channel B input on the counter IC,
U56. This pulse is initiated by the p-controller pulse CAL-
TEST-PULSE.
4~8 Hardware Functional Description
Trigger Level Circuits
The trigger level circuits generate the trigger levels to the
A and B inputs. The trigger level range is -5.1 V to + 5.1 V
with a resolution of 1.25 mV. As the input amplifier attenua-
tion is approximately about 2.4 times, the trigger level cir-
cuits generate a DC level that has the same attenuation.
This means that the output of this circuit has a range of-
2.2 V to +2.2 V with a resolution of 0.5 mV. To get the
high resolution, two 12-bit DACs are used. The supply vol-
tages to the trigger level circuits are filtered to prevent noi-
se from the digital circuitry to influence the trigger level,
(see Figure 4-11).
The trigger level circuits consists of:
- Reference voltage circuit (2.5 V), (U86).
- Reference voltage inverter circuit (-2.5 V), (U59).
- A multiplexer to select positive or negative reference
voltage and Full scale B or Full scale common B trim-
mers, (U60).
- Buffer circuits, (U61 and U62).
- Two Digital to Analog converters, (U63 and U64).
-Two current-to-voltage converters (U65 and U66). These
circuits convert the current at the lOUT pins of the DACs
to a voltage. This signal has a range of approximately
-2.1 Vto 2.1 V.
- Two output buffers and RC filters for the trigger level out-
puts on the rear panel. (U67).

Power Supply
• Primary Circuits
The power supply generates five regulated DC supply volta-
ges to the counter. It also generates some other supply vol-
tages for special purposes. The power supply block also
contains the ON/STANDBY logic, (see Figure 4-12).
The main building-block of the power supply is the primary
switch mode power circuits. A rectifier make a DC-voltage
of the line power AC-voltage (90 V to 265 V), before it is
fed to the switch circuits.
After a line-power filter in the power inlet, a fuse and an
NTC-resistor protect the power supply. The fuse (FI)
should only blow if a catastrophic error occurs on the pri-
mary side of the power supply, A short-circuit on the secon-
dary side should not affect the primary side. To minimize
the "current rush" to the capacitors at the connection of the
power cord, an NTC-resistor (R337) is used. The resistan-
ce is 16^2 when the resistor is cold, but decrease to a few
ohms when warmed up by the current. The AC voltage is
rectified in the bridge rectifier D40 and filtered in C330.
Cl 81, Cl 83, and Cl 84 should suppress noise from D40.
L20, Cl 73, and C174 forms filters.

L39 and L40 prevent HF-noise from the switch circuitry to
reach the line-power inlet.
R460 to R463, R467, and R468 gives the start up voltage
to the control circuitry U91. U91 outputs a frequency of
120 kHz on OUT (pin 10) to the switch transistor V55.
When the switch transistor has started U91 will be supplied
from the transformer T1 pin 3 via the diodes D50A and
D50B.
Every switch pulse causes a voltage drop over the resi-
stors R471 to R473 and R558. This voltage feeds the SEN-
SE input (pin 5) of the control circuit U91. When the volt-
age has reached the internal reference level in U91, the
switch transistor V55 is turned off.
V60 is a blanking transistor that will compensate for high
transients generated by the transformer T1.
The internal sawtooth generator RC (pin 7) in U91 is con-
nected to the SENSE input via V57, to compensate for low
load.
The regulated +5 V is senced by U92 and adjusted by
R446. The output of U92 is connected to the VF input (pin
3) of U91 via the opto coupler U90.
The VREF pin (pin 14) outputs a reference voltage of 5 V
DC.
• Secondary Circuits
A voltage over the capacitor C373 is generated by the dio-
des D56A and D56B. This voltage is used to generate a
power-failure interrupt, (NMI) to the p-controller, when the
line-power disappears, (see Figure 4-13).
From the module there are three DC voltages outputs. One
of those is regulated (+5 V) and the others are unregula-
ted. These voltages will vary with input line voltage, the cur-
rent at +5 V, and at the unregulated voltages. The output,
marked +15, will be 14.8 V to 21 V and the output , marked
-9, will be -12.5 V to -7.5 V. The outputs are filtered, HF-
filtered by C176, C177, and C178 and LF-filtered by L19,
L21, L22, C179, C329, and C333.
These three DC voltages are used to make the following
five supply voltages in the counter:
+5 V
From the switch transformer T1 via D43 and regulated by
V49 and U72..
-5.2 V
-9 V is regulated by VI 7, U73, and U74.
+12 VREG
+15 V is regulated to +12 V by U69.
+12 VREG is used for the optional oven oscillator and the
STAND-BY indicator.
+12 V
+12REG V is swithed on and off by +5 V via VI 8 and V48.
+7 V
U70 and U71 regulates +12 V to be +7 V.
The voltages for special purposes are:
4-10 Hardware Functional Description
+9 V
Used unregulated.
At stand-by, the regulated supply voltages except
+12VREG are switched off. However some special volta-
ges are not, because the oven oscillator should be on and
the ON/STANDBY logic should function, therefore, the pri-
mary power circuits will never be switched off. PM 6681
has only a secondary power switch.
A relay (K1C) disconnects the load of the +5 V and -5.2 V
at stand-by. Because the power circuits always must have
a load on the regulated voltage, a bleeder resistor R349 is
always connected to +5 V. At standby the counter oniy
needs +12 V, and to get enough current of this voltage, a
certain current of the regulated +5 V must be used.
+5 V controls the switching on/off of +12 V and +7 V.
When +5 V is on, V48 conducts, and the base of VI 8 will
be approximately +1 1 V and the transistor will conduct, i.e.,
+12 V will be on. If there is no +5 V, V48 will be off, and
the base of VI 8 will be +12 V, thus blocking the +12 V.
The ON/STANDBY logic controls relay K1A, which opera-
tes as described above. J15 have three functions:
Normal K1A controlled by the ON/STANDBY
logic.
Removed K1A allways open.
Ground K1A allways closed.

outputs an analog signal to the p-controller U6. The p-con-
trolier also senses the temperature on the main PCA via

4-12 Hardware Functional Description
Counter Circuits
The PM 6681 measuring logic consists of two ASIC’s: One
high speed bipolar ECL circuit and one CMOS circuit The
bipolar SMTC, (U56) contains the measuring control
functions, high speed counters and some analog parts
used to increase the time resolution. The CMOS ASMTC,
(U58) consists of two counter chains for the measurement
and logic for measuring the expanded interpolator pulses.
It also contains two programmable mono flip flops (100 ns
resolution), an oscillator and an external reference input,
(see Figure 4-16).
Interpolator
The bipolar circuit has a small analog part. This part increa-
ses the resolution in time and frequency measurements by
means of an analog interpolator. An analog interpolator is
basically a capacitor charged and discharged with different
currents (ratio approximately 400). A small error pulse is
extended with the ratio of these currents, (see Figure 4-14).
Figure 4~1G The interpolator expands the error pulse
400 times.
ked with 100 MHz when the signals IPA and IPB are pre-
sent. After the counter circuit the signal is fed to OQ0504,
U56, to be measured.
Timing
The following timing diagram (Figure 4-17) shows a num-
ber of measurement signals for a frequency measurement
of 11 periods. This measurement is started directly when
reset is released. The measurement start can be controlled
in a much more detailed manner. GET and arming delays
(event or time) can be used to qualify the measurement
start. Qualifying the stop can be done in the same advan-
ced way. The basic method is to send a Measurement
STOp (MSTO) signal to the circuits via the \iC interface.
This signal cannot be viewed externally.
The length of IPA and IPB is not correctly viewed (approxi-
mately 3 to 7 s).

Using the standard clock frequency as a reference we can
measure this new extended pulse length. There are two in-
terpolators, one start and one stop interpolator. OQ0502,
(U58) circuit includes the generation of the error pulse and
the time expander. OQ0504, (U56) holds the measuring lo-
gic for the expanded pulse. The small error pulse is the
time from the external trigger event to the second positive
clock transition. Consequently, the error pulse is between
10 ns and 20 ns long. The extended pulse is approximate-
ly 3 to 7 ILLS, (see Figure 4-15).
Figure 4-17 Measuring the expanded pulse In the
OQ0504 and the external counter.
Very fast events can not be handled by the counter cir-
cuits. Therefor some externa! interpolator circuits have
been added to the interpolator circuits located inside
OQ0502, U58. The counter circuits, U39 and U41 are clok-
Figure 4-15 A number of measurement signals for a
frequency measurements of 11 periods.
XCY (X carry) is the input signal divided by 8. YCY (Y car-
ry) is the clock divided by 8 ( 12.5 MHz ). These two si-
gnals will normally look like a burst signal of 12.5 MHz and
the input signal divided by 8. The burst length is as long as
the gate time. An OverFLow Warning message, OFLW is
send to the OQ0502 circuit. This means that the counter
chains in OQ0504 will soon overflow and that the start/stop
logic should stop the measurement when possible.
Reset
The RESET signal is coupled as a ripple through chain. By
this method the reset signal resets the whole measuring lo-
gic in a correct order. The reset chain starts at the RESET
IN pin on OQ0504, ripples through the measuring logic of
OQ0504 and comes out on RESET OUT. The RESET si-
gnal is clocked through a flip-fiop by the 100MHz signal
and is then connected to the RESET IN pin of OQ0502
and resets the measuring logic of OQ0502.
The TRA and TRB signals are directly controlling the trig-
ger LED’s on the front panel. C315 and C316 connected to
TRAC and TRBC inputs control the blinking rate.
Arming Delay
The measuring logic also has a programmable delay with a
resolution of 100 ns. This delay is used as arming delay
and is generated in the OQ0504. it is triggered from
OQ0502 by the signal ARDO (to SYN1 in OQ0504). Toget-

her with the signal PD1 from OQ0504, the delayed signal
is fed back to the ARDI input on OQ0502. Instead of a
time delay, the delay can be programmed to an event de-
lay. The EDC1 input of OQ0504 are therefore connected to
the B input enabling, event delay for events on the B chan-
nel.
Hold-Off
A second programmable delay with a resolution of 10 ns is
used as hold off. It is triggered from OQ0502 by the signal
HOS. The counter U53 is loaded with a value and clocked
with 100 MHz. When the counter has come to zero this in-
formation is sent to OQ0504, EDC2 and the circuits are re-
seted.
The delayed signal is fed back to the HOF input on
OQ0502.
Gate Open
The signal GATO from OQ0502 gives a real time indication
of the state of the measuring logic. Main gate open is indi-
cated by a high level and main gate closed is indicated by
a low level. VI 22 makes it possible to make the high level
1.4 V in 50a.
Divider
The signal from input A is divided by two during frequency A
measurements by the divider U85. The reason for this is that
the OQ0502 can not handle frequencies above 225 MHz.
To be able to measure frequency bursts also on input C the si-
gnal from the prescaler is divided by two by the other half of
U85 before it enter the OQ0502..
Inputs
The signals A (A-channel), B (B-channel), C (prescaler si-
gnal), and E (rear panel external arming input) go to an in-
put multiplexer in OQ0502, In OQ0502 the A and B inputs
also have slope selections (positive edge and negative
edge). R257 and C117 terminates the C signal.
External Arming
The rear panel input EXTERNAL ARMING is a DC-coupled
TTL level input. R258 to R261 with D32 and D33 protects
the input. V8 and V42 are a Schmitt-trigger with approxima-
tely 1.4 V threshold level. The external arming signal is
connected to E input on OQ0502.
Burst
The signal HOS from OQ0502 are also used when measu-
ring at bursts. The External Arming input is switched off by
the signal HS0.4 from the iti-processor via V66 and V65.
The HOS signal is then fed via V68 and V67 back to the
OQ0502 input E.
All ECL-inputs in OQ0502 get their reference (VBB) from
an external ECL-circuit U132.
The GET-signal from an optional GPIB-interface can con-
trol the start of the measurement.

Oscillator Circuits
• CPU oscillator
The ii-controiler U6 works with 16 MHz. A 16 MHz crystal
B1 is connected to the XTAL inputs of the p-controller.
This frequency is divided by two by the p-controller and is
used by the GPIB controller U78.
• standard oscillator
The 10 MHz reference oscillator is used as a reference for
the measuring logic, (see Figure 4-18).
For the interna! oscillator, there are several optional oscilla-
tors to choose from. The uncompensated 01 -oscillator is al-
ways mounted in the PM 6681. If a better oscillator is nee-
ded, it should be connected to the opt.osc connector PI 05.
A TCXO PM 9678B, oven oscillator PM 9690, or oven oscil-
lator PM 9691 can be mounted, if this is done the oscillator
type jumpers J12 should be placed in the OPT position.
The 01-oscillator consists of a crystal B2, C107 to C109,
R239, R240, and the trim capacitor Cl 14. Cl 14 adjusts
the frequency.
If an optional oscillator is mounted, the 10 MHz signal is
amplified in a two stage amplifier (V40 and V41).
• External Reference Input
The external reference input can handle frequencies in
steps from 1 MHz to 10 MHz, (1, 1.111, 1.25, 1.4285,
1.6667, 2, 2.5, 3.3333, 5, & 10 MHz).
R276, R278, and D35 protect the input. U88 amplifies the
signal and make nice pulses out of it. U37 generates short
pulses which is then filtered in the crystal filter B5 to be
10 MHz, (see Figure 4-19).
It is possible to switch off the external reference signal with
the signal DISABL-EXT-REF from the micro controller. A
low level of this signal makes V61 conductive, and that for-
ces a high ECL-level on the output of U98.
The selected reference is used as 10 MHz out. An ampli-
fier stage, V9 transforms the square wave from U56 to a
sine signal. This stage has 50 O. driving capabilities.
• 100 MHz Frequency Multiplier
The 10 MHz reference signal is fed to the flip-flops U81,
which generates short negative pulses, (see Figure 4-20).
These pulses triggers the resonant circuit, L25, C414, tu-
ned to 100 MHz. After the amplifier V20, the signal is
again fed to a resonant circuit, L29, C346, tuned to
100 MHz. A 100 MHz filter B3 removes over- and underto-
nes. this procedure is repeated to get a nice sine wave.
U94 generates a sqare wave signal which is used directly
by the external Interpolator counter and Hold-off circuits.
The 100 MHz sqare wave is also converted to ECL levels
by resistors R238, R266, and R432, and used by OQ0502
as reference.

Logical Circuits
• Microcomputer Circuits including. I/O
The microcomputer in PM 6681 is an Intel 16-bit CHMOS
lacontroller 80C196KC16, U6. It is a fast micro controller, in-
tended for controller applications, i.e., it has many I/O ports
and other facilities to control and react on the external
world. It contains 232 RAM-bytes, (see Figure 4-21).
The micro controller can operate in both 8 and 16-bits
mode externally. Internally the micro controller uses 16-
bits. The address and data-bus ADO to ADI 5 is shared
(time multiplexed) between addresses and data. Therefore
the address must be stored in an address-latch (U14 and
U15) by using the signal ALE (pin 62).
If the surrounding circuits are slow compared to the micro
controller, wait states must be issued. The ready-pin (pin
43) goes low to get wait states. When the micro controller
communicates with the battery RAM, the GPIB-chip, the
ASIC;s, and the trigger level circuits, wait states are auto-
matically Inserted.
The PROM;s (U16 and U17) used is a 27H010, i.e., two
128K byte memories. The address mapping is done so we
can only address 32K bytes directly. Bank switching is
4-16 Hardware Functional Description
used to be able to use all 128K bytes. The signal from U6
pin 21 and 22 controis that one quarter of the memory is
used for the moment. At reset the first quarter is seiected
(U6 pin 21 and 22 goes high).
To be able to make a CRC-check of the contents of the
PROM, the micro controlier must be able to read the con-
tents of the PROM as data.
The address and data bus ADO to ADI 5 can be separated
into two parts. By removing resistors R183 to R190, R209
to R212, and R221 to R224 you can separate the micro
controiler, the address latch and the PROM from all other
circuits on the bus. By removing R225 to R232 you can se-
parate the counter circuits and the GPiB controller from the
AD-bus.
The micro controiier communicates with the outer worid by
I/O circuits connected to the address and data bus ADO -
ADI 5, The WR (pin 40) and RD (pin 61) signais from U6
controi the direction of information. These two signais, with
the address decoding iogic, produce "chip select" signals
for the I/O circuits. The address decoding iogic uses the
A5 - A15 to produce chip seiect signals. Chip select si-
gnais are generated for:
- PROM, U16 and U17, and RAM, U9 to U13.
“ The input amplifier relay driver U18, display scanning cir-
cuit U19 and U20, and the GPIB driver U78.
“ The trigger level circuits U63, U64, and U60 and the
counter circuits U56 and U58.
To show that the counter measures, a gate indicator is pla-
ced on the front panel, it is controlled from the micro con-
troller U6 pin 28 via V54. The blinking of the LED is softwa-
re controlled, and does not necessarily reflect the true sta-
te of the measuring hardware.
The RAM, U13 has battery backup. If the counter is ON or
in STAND-BY, the +12VREG gives power to the RAM pin
28, via U7 and D30 to get +5 V. If the counter is not con-
nected to the line power at all, the 3 V battery gives power
to the RAM. The Schottky diode D31 isolates the battery
and preserves power when +12VREG is present. When
this happens pin 27 of the RAM is low, and the RAM goes
to the power-down mode. At this point the RAM needs a
2 V supply voltage.
The version of the main PCA are identified by the resistors
R524 and R525. This DC voltage are fed into the analog in-
put ACHO of the p-controller U6, which recognizes the bo-
ard. This makes it possible to make the software backward
compatible.
The different prescalers are identified in a similar way.
R1 92 to R1 94 and R203 to R204 forms a resistor network
that generates different DC voltages at the ACH1 input of
the p-controller. This DC voltage depends of how the pins
12, 14, and 16 on P20 are connected to ground and +5 V
on the prescaiers.
• Reset Circuit
A special reset circuit is included in the design. U8 is a spe-
cial supply supervisor, if the +5 V becomes lower than
4.5 V, the reset output pin 4 goes low. This gives a micro
controller reset. For test purposes the micro controller can
be forced to reset by short circuiting the pads J10. The
length of the reset pulse is set by C310; 2.2 pF gives a pul-
se of approximately 40 ms. The supervisor circuit also con-
trols the reset pulse during the power-on, so the micro con-
troller starts in a controlled manner.
• Keyboard Scanning
Figure 4-22 Keyboard scanning.
All outputs of U19 are set low one after the other, if no but-
ton is pressed, all outputs to the latch U20 are high and so
are the inputs to the AND gates U21 and U87, (see Figure
4-22).
When a button is pressed, one input on the AND gates will
go low. An interrupt is generated to the |i-controller U6 pin
P0.7. The p-controller reads the latch U20, and the pro-
gram jumps to a special handler in the SW.
The ON button are connected to the ON/STANDBY logic in
the power supply. When the counter Is in STAND-BY the
RESET input (pin 10) of U76 is kept high and so are the
outputs of U76. A press on the ON key will discharge the
capacitor Cl 80 via the diode D24, the ON switch and the
resistor R337 to ground. Pin 5 on U76 will go high making
the transistor V52 active and the relay K1 will draw. Furt-
her more a short pulse is generated at V7 telling the p-con-
troller that the ON button have been pressed. This makes
it possible to sense the difference between plugging in the
line power cable or pressing the ON button.
When STAND-BY is pressed the p-controller sets the flip-
flop U76 by the signal SET-STAND-BY and the relay K1
will fall.
The LOCAL/PRESET button are connected directly to the
AND gates U21 and U87.
The STAND-BY indicator on the front panel is controlled by
the +5 V, via V51 . +5 V off lights the STAND-BY LED.

GPIB Interface
Figure 4-23 GPIB interface.
The GPIB interface controls the communication between
the internal microprocessor and the external GPIB bus,
(see Figure 4-23).
Communication between the GPiB control circuit, U78,
and the external GPIB bus is done via the bi-directional
bus drivers U79 and U80. U78 is controlled from the micro-
processor by writing and reading in the internal control regi-
sters. if U78 has a message for the microprocessor, it
uses the GPIB interrupt signal. The address of the GPIB
bus is software controlied.
U9 to U13 are the RAM used to execute the program. U14
and U15 are address iatches.

Optional Units
HF Inputs
There is a choice of three different optional HF inputs;
PM 9621, PM 9624, and PM 9625, The inputs are all
mounted on the same place on the main board, to the right
of the input amplifier. They are connected to PI 07, and
only one prescaler at a time can be mounted. In BU7 there
are 3 ID pins. Different prescalers have different coding of
these pins. PM 9624 and PM 9625 are factory repair only,
due to the need of Instrumentation for high frequencies.
• Prescaler 1.3 GHz, PM 9621
Figure 4^26 PM 9621 Block diagram.
The frequency range for the prescaler is 70 MHz to 1.3
GHz. To be able to be handled by the measuring logic in
the counter the frequency is divided by 256. The input is
AC-coupled and the input impedance is 50^2 nominal. Five
main blocks makes the prescaler: Limiter, amplifier, divider,
ECL output, and ievel detector, (see Figure 4-26).
Limiter
The 6 dB attenuator (R1 to R1 1) keeps the VSWR \o\n for
all input levels, even the PIN diodes have low impedance,
(see Figure 4-27). When the peak-to-peak level of the in-
put signal is greater than the sum of the voltage drops of
the Schottky diodes GR3 and GR4, the charging of capaci-
tor C4 starts. Capacitor C4 filters the voltage after the
Schottky diodes. The PIN diodes GR11 start to conduct
when the voltage is lower than approximately -0.65 V.
More current through the diodes means lower impedance.
This means that the HF voltage over GR1 1 is constant.
R12 discharges C4 then the input level decreases. LI pre-
vents capacitor C4 from short-circuiting the HF signal.
Amplifier
R13, R14, and R15 attenuate the HF signal 3 dB, to pre-
vent overloading of the amplifier circuit IC1. 1C1 amplifies
the HF signal approximately 15 dB. TS1 amplifies the fre-
quency range 0.9 to 1.4 GHz by 8 dB, to increase the le-
vel for these frequencies due to the falling frequency re-
sponse of IC2. TS2 is an impedance converter, (see
Figure 4-28).
Divider
Figure 4-29 Divider and ECL-converter circuits.
The divider 1C, 1C2, divides the input frequency by 256.
The output frequency is max. 5.5 MHz, (see Figure 4-29).
ECL output
TS3 and TS4 convert the output signal from 1C2 to ECL le-
vels. The rise and fall time of the output signal must be
shortened. This is done in the differential amplifier TS5 and
TS6. TS7 restores the ECL levels and buffers the single en-
ded output signal, (see Figure 4-29).

Level detector
Prescaler 2 . 7 GHz, PM 9624
C13, C16, and L6 form a filter making the frequency re-
sponse of the signal to the level detector diode GR7, the
same as the signal to IC2, (see Figure 4-30).
The detector voltage is filtered and fed to IC3. Diode GR15
prevents the level from being too negative (IC3 is then lok-
ked). The first stage in 1C3 amplifies the level approximate-
ly 15 times and the second stage is a Schmitt trigger. The
output from the Schmitt trigger can block, via TS8, the ECL
output signal. A low output signal from 1C3 pin 7 makes
TS8 conduct. The ECL output signal will be 4.5 V. If IC3
pin 7 is high, TS8 is not conducting, and the output signal
from TS7 is not blocked. The Schmitt trigger is controlled
from the first amplifier in 1C3. If the level on IC3 pin 3 (de-
tected level) is lower than the reference ievel on IC3 pin 2
(an HF signal with sufficient level present), ICS pin 1 is low
and the Schmitt trigger output is high, thus not blocking the
ECL output signal. The reference level on 1C3 pin 2 Is set
by trim-potentiometer R30. GR8, GR9, and R28 form a
temperature compensation circuit, to compensate for the
temperature behavior of the detector diode GR7. Forte-
sting purposes, the level detection can be overruled by the
signal TEST GO. A high level makes TS10 conduct, and
that enables the ECL output signal, despite the HF input si-
gnal amplitude. The ECL output signal can also be swit-
ched off, despite the level detection. A high level on signal
NOT C makes TS9 conduct and thus makes the level to
TS8 low. TS8 makes the ECL output signal +4.5 V.
Figure 4-31 PM 9624 Block diagram.
The PM 9624 prescaler cannot be repaired at a local
workshop. It must be sent to the factory for repair.
The prescaler consists of the following parts, (see Figure 4-
31):
Limiter
- The limiter consists of a 6 dB attenuator and a PIN diode
attenuator, to achieve constant input amplitude to the
amplifiers.
Amplifier
- Five amplifier stages are divided into three blocks. One
block consists of one amplifier. Two blocks consists of
two amplifiers each and an AGC control.
Automatic Gain Control (AGC)
- Helps the amplifiers to retain a constant output amplitu-
de.
Dividers
- Two dividers divide the input signal frequency by 16.
Detector
- Detects whether the level of the input signal is high
enough to ensure correct measurement and, if not,
blocks the output signal from the prescaler.
Positive Voltage Regulator

Repair
Preventive Maintenance
Calibration
To maintain performance of PM 6681 we recommend that
you calibrate your instrument every year, or more often, if
greater time base accuracy is required. Calibration should
be performed with traceable references and instruments at
a certified calibration laboratory. Contact your local Fluke
service center for calibration.
To know the present status of your instrument, test your ti-
mer/counter from time to time. The test can be made accor-
ding to the information in Chapter 2, Performance Check.
Oscillators
The frequency of the reference crystal oscillator is the
main parameter affecting accuracy in a counter. The fre-
quency is affected by external conditions like the ambient
temperature and supply voltage, but also by aging. When
recalibrating, the reference crystal oscillator is compensa-
ted only for deviation in frequency due to aging.
• Some important points:
- The high stability oscillators have been built into an oven
in order to keep the oscillator temperature as stable as
possible. Continuous operation is also important for sta-
bility. After a power interruption, the oscillator restarts at
a slightly different frequency. It will then, as time goes
on, age at an equal rate.
- The stability indicated for the oscillators is valid within a
temperature range of 0 to 50°C, with a reference tempe-
rature of 23°C. If the timer/counter is used in a room
temperature of 20 to 30°C, the temperature stability of a
TCXO or OCXO will be increased by a factor of 3.
- The temperature stability indicated for TCXO and stand-
ard oscillators are mainly dependent on the ambient tem-
perature. When operating there is always a temperature
increase inside the counter which will influence the oscil-
lator.
• Recaiibration intervais
The Mean Time Between ReCalibration, MTBRC, is defi-
ned as:
MTBRC =
{Acceptable error) - (Temperature stabiiity )
(Aging )
MTBRC can be calculated when the total acceptable error
and the oscillator specifications are known.
The total acceptable error is defined as:
(PeviatiorDf reference frequency)
{Nominal frequencyreference )
(Acceptableerror) ='
Example:
- A user can accept a maximum of 3 Hz deviation on the
10 MHz frequency of the oscillator. This results in:
{Acceptableerrot )= — x = S^i^lO"^
10 * 10 ®
The aging and temperature factors can be selected from
the table on page 5-3.
The value of the aging factor is correctly selected from the
table when the calculation of MTBRC results in 1 to 30
days (use /24h), 1 to 12 months (use /month) or over 1
year (use /year) (not, e.g., 43 days or 17 months or 0.8 ye-
ars).
Example:
— The user has the same requirements as in the example
above. The counter has a PM 9690 oscillator.
- Look up information about PM 9690 in the table on page
5-3. The results will be the following:
Relative Frequency deviation caused by:
• Ambient temperature deviation
(within 0 to 50°C; reference point at 23°C): Less than
1.5 * 10“®
• Aging/year: Less than 1 * 1 0“^
“ Use the MTBRC formula with the above values. This gi-
ves a MTBRC of maximum:
(3*1 0~^)-(1 .5*10"°

caused by aging.

Battery Replacement
To preserve data and variables needed for the use of
PM 6681 a lithium battery is included. The lithium battery
has an estimated lifetime of five to ten years. We recom-
mend an replaceing the battery every five years to avoid
loss of data in operation.
When battery Is empty, the timer/counter will lose all set-
tings, and any data in memory, if disconnected from line
power.
See "Reinstalling the Battery" on page 3-4.

Troubleshooting
General
Quick Troubleshooting
The PM 6681 is a highly integrated Timer/Counter with de-
dicated LSI counter circuits and microcontrollers that con-
trol the complete units. The microcontroller can help you to
locate faulty parts by running test programs and generating
stable signal patterns on the bus. If the microcontroller
does not work or the fault is in a part of the counter that
cannot be accessed by the microcontroller, traditional fault-
finding must be performed.
Where to Start
After reading the safety instructions, continue with this Chapter
for faultfinding and repair instructions. When you have fixed
the instrument, always do the Safety Inspection and Test after
Repair, as described later in this Chapter. Then do the checks
in Chapter 2, Performance Check. Recalibrate if required by
following the adjustment instructions in Chapter 6, Calibration
Adjustments.

The troubleshooting strategy in PM 6681, is an integrated
part of the overall service strategy for the instrument. This
instrument is hierarchically designed in different levels, see
Figure 5-4, and troubleshooting can be performed in any
design level if the lower levels are OK. It is therefore impor-
tant to disconnect all options in the beginning of the trou-
bleshooting procedure.

Troubleshooting 5-5
Power Supply (Functional Level 1)
Figure 5-7 Test points and voltages for the power
supply.
WARNING: Live parts and accessible terminals
which can be dangerous to life are always
exposed inside the unit when it is connec-
ted to the line power. Use extreme caution
when handling, testing or adjusting the
counter.
Primary circuits
To verify the Power supply proceed as follows:
- If the primary fuse is broken, there is a short circuit in
the primary circuits. Use a DMM and try to iocate the
fauit by resistance measuring.
- Remove the cover from the Power Supply.
WARNING: The heat sink inside the power
supply is connected to the line power.
- Disconnect L39 and L40 and check the resistance be-
tween pin 1 and 4 on the transformer T1, see Figure 5-7.
if the DMM show a short circuit the fault is proabably a
broken transistor V55. Put L39 and L40 back in position.
- Connect the counter to the iine power via an insulating
transformer with separate windings.
- Set the counter to STAND-BY mode.
- Check that the voltage between P19 and P23 is in the
range of 90 to 260 Vac.
- Check that the DC voltage between pin 1 and 4 on T1 is
about -^2 times the input AC-voitage. if not, use traditio-
nal fauitfinding techniques to locate the fault.
- Remove the jumper J15.
- Check the "STAND BY" voltages according to Table 5-5.

- If one or more bits on the AD-bus are corrupt, the pC
often reads the same instructions repeatedly. When
the pC discovers are invalid OP code, it will RESET
itself and start from the beginning again. The pC sets
the RESET input low when it resets itself. This can be
discovered at the RESET input of U6, (pin 16). If +5 V

NOTE: The timer/counter, synthesizer, and the pulse gener-
ator should not have the same GPIB address, none of
them should have address 0 or 30, (this is used by the
PC).
• Adjustment
— Turn on the timer/counter, the synthesizer, and the pulse
generator.
If the timer/counter shows a flashing zcal.lostz, press
the preset button until this message disappears.
NOTE: The calibration should be done when the counter has
been on for more than 20 minutes. If you start the ca-
libration program before 20 minutes has passed since

“ Insert the discette labeled "Test and Calibration program
for PM 6681", into the 3 V 2 " disc-drive on the PC.
- Start the calibration program from the DOS command
prompt with the command "[path]CALVER81". Suppo-
sing you use the A: drive, this might look like:
C:\ >a:CALVER81
The first displayed screen on the PC will show you the nee-
ded hardware and software to run the calibration program.
It also shows the bus addresses the different instrument
must be set to.
- Press ENTER when you are ready to begin the calibra-
tion.
- Now you shall enter the different GPIB addresses for the
instruments involved.
- Type the serial number of the counter under test and
press ENTER.
Now you will be asked if you want to calibrate the counter.
The calibration will take between 20 and 60 minutes to
complete. (If you answer no (n) on this question you will be
asked if you want to verify the calibration of the interpola-
tors. The verification will only take a few minutes.)
The program will attempt calibration using a number of dif-
ferent input signals, and will check the result, choosing for
the final calibration the best result achieved.
After the calibration is completed the best calibration para-
meter will be stored in the counters battery backuped
RAM. A printout of the calibration result will also be sent to
LPT1 of the PC. The printout will look as shown below:
NOTE: Even though the specification says 50ps the system
does not accept more han 40ps. This limit is set to en-
sure that the spec should be fulfilled over the whole
temperature range.

Replacement Parts
Introduction
standard Parts
Electrical and mechanical replacement parts can be obtai-
ned through your local Philips or Fluke organization or rep-
resentative. However, many of the standard components
can be obtained from other local suppliers. Before purcha-
sing or ordering replacements parts, check the parts list
for value, tolerance, rating, and description.
If the value of the physical component differs from what is
described in the parts list, you should always replace the
part with the same value as originally mounted.
Special Parts
In addition to standard electronic components, the follo-
wing special components are used:
- Components that are manufactured or selected by
Philips to meet specific performance requirements.
- Components that are important for the safety of the
instrument.
Both type of components may be replaced only by com-
ponents obtained through your local Philips or Fluke or-
ganization.
NOTE: Physical size and shape of a component
may affect the performance of the instru-
ment, particularly at high frequencies.
Always use direct replacements unless it
is known that a substitute will not degrade
the performance of the instrument.
The abovementioned parts are ‘Recommended Replace-
ment Parts’ and are marked with an ‘R’ in the ☆ column
of the parts list.
Componenets marked with a ‘P’ in the ☆ column are ‘Pro-
duction items’ not kept in replacement parts stock. These
items can be ordered, but the delivery time is longer than
for normal replacement parts.

Diagrams
How to Read the Diagrams
This chapter contains circuit diagrams and component layout in-
formation.
Each diagram contains a list of the ICs used. These lists indica-
tes the connections that are not shown in the diagram, such as
GND and supply voltages.
Signals
The signals in the counter are named after what they do, e.g.
LEAD-EDGE is used as control current to the leading edge cir-
cuits.
Two different types of arrows are used to mark references for
continued connection somewhere else in the diagram.
~t>
This arrow is used if the reference is directed to a
point located on the same page.
~\y
/1 .A1 Thjs arrow is used if the reference is directed to a
point located on another page. The example means that the
point is on sheet 1, coordinate A1.
Colored Areas
The coloured areas in the diagrams represent following
functions:
= Integrated circuits
I I = Trim points, test points or jumpers
= Connectors
Circuit Symbols
The diagrams are computer drawn. The symbols conform to
lEC standards. These symbols are designed to be logical and
easy to read.
The component number is written above the symbol.
Inside the symbol at the top is an abbreviated description of the
circuit’s function.
Pin numbers are written outside the symbol and, if the circuit is
complex, the pin functions are written inside.
A small circle on a pin indicates that the input/output inverts the
signal.
The component name is written below the symbol.
The signal flow through the circuit is always from left to right.
Resistors, Capacitors, Diodes,
Transistors and Other Components.
These components are similar to the old-fashioned, hand-
drawn symbols. They have their component number above and
their value or component name below.
A resistor contained In a resistor network has a frame drawn
around it and one of the pin numbers is written to the left or be-
low it.

9-2 How to Replace Surface Mounted Devices
I
Electrostatic discharge
Almost all modem components have extremely thin conductors and
metal oxide layers. If these layers are exposed to electrostatic dis-
charge they will break down or perhaps even worse, be damaged in a
way that inevitably will cause a breakdown later on. The Elec-
tro-Static Discharge sensitivity of MOS and CMOS semiconductors
have been known quite a while, but nowadays bipolar semiconduc-
tors and even precision resistors are ESD sensitive. Consider there-
fore all components, pc-boards and sub-assemblies as sensitive to
electrostatic discharge. The text below explains how you can mini-
mize the risk of damage or destroying these devices by being aware
of the problems, and learning how to handle these components.
ESD sensitive options are packed in conductive containers marked
with this symbol.
• Never open the container unless you are at an ESD pro-
tected work station.
• Use a wrist strap grounded via a high resistance.
• Use a grounded work mat on your workbench.
• Never let your dothes come in contact with ESD sensitive
equipment even when you are wearing a grounded wrist
strap.
• Never touch the component ieads.
• Never touch open connectors.
• Use ESD-safe packing materiais.
• Use the packing materiai only once.
• Keep paper and nonconductive plastics etc. away from your
workbench. These may biock the discharge path to ground.

Unit 1
The main printed-circuit board (Unit 1) has recently been rede-
signed due to obsolescence of a number of integrated circuits.
Designations found in circuit descriptions, schematic diagrams
and parts lists in the first eight chapters refer to the original de-
sign. The functional descriptions are correct on the whole, if you
make a few substitutions. Anew set of schematic diagrams and a
new replacement parts list are included in this chapter.
- Instruments having serial numbers >784919 belong to the
new generation.
- The model PM6681R/676/AF has only been produced with
the new Unit 1 board, so the serial number is irrelevant in
this case.

Model PM6681R
Rubidium Timebase
Introduction
A rubidium timebase (atomic clock reference) is now available in the
Model PM6681R Timer/Counter/Analyzer. This oscillator cannot be
retrofitted. Due to the power requirements, an additional built-in
power supply is needed. It is located on the same board as the distri-
bution amplifiers for the six extra reference outputs included in this
instrument.
Performance Check
The general rules in Chapter 2 apply, but observe the additional in-
structions below.
NOTE: To fully test the accuracy of the PM6681 R, access to
an extremely high stability reference signal is needed,
for example a Cesium Atomic Reference or a transmit-
ted signal from a nationally or internationally traceable
source. Additionally the instrument has to be stabilized
for a period of one month.
The PM6681R has an UNLOCKED/STANDBY LED. When the
LED is lit the Rubidium time base is still in its warm-up phase and is
not yet stabilized.
■ Test procedure
- Connect the counter to the line power.
- Check that the UNLOCKED/STANDBY LED is lit.
- Turn on the Timer/Counter
- Check that the UNLOCKED/STANDBY LED is switched off
within 5 minutes after connection to line power.
- Connect a 10 MHz reference signal to input A of the counter.
- Select FREQUENCY A measurement.
- Select 1 s measuring time.
- Check that the displayed frequency is 10.00000000 MHz ±
1 LSD < 6 minutes after connection to line power.
NOTE: The rubidium timebase unit must be sent to a Fiuke
service center for repair. Follow the exchange proce-
dure.
Calibration and Adjustment
NOTE: Before adjusting the oscillator, the timer/counter must
have been continuously connected to the ac power
line for at least 24 hours.

m Setup
— Connect the 10 MHz reference to the REFERENCE IN con-
nector on the rear panel of the timer/counter and make sure
that External Reference is selected on the firont panel.
— Connect one of the 1 0 MHz outputs on the rear panel of the
PM6681R - the Device Under Test (DUT) - to Input A of the
timer/counter.
■ Calibration measurement
-Set the measurement time of the timer/counter to 10 s.
— Select MATH (K*X+L) and set a negative offset of 10 MHz (L
= -10E6).
— Select STAT (statistics), N=100, and MEAN.
— Press RESTART. After approx. 17 minutes the mean value
over 100 readings is displayed.
NOTE: If a GPS receiver is used as a reference, change num-
ber of samples N in the STAT menu to 8640 (instead of
100) to enable a frequency mean value over 24 h (in-
stead of 17 min). GPS receivers have an excellent
long-term stability (24 h) but can be quite unstable
over shorter periods.
■ Adjustment criteria
_3
If the display reading does not exceed 0.5 mHz (0.5x1 0 Hz), no ad-
justment is required.
■ Adjustment procedure
— Switch off statistics (STAT OFF) in the timer/counter.
— Remove the seal sticker fi:om the front panel of the DUT (be-
low ‘Ref Adj’ to the left of the PRESET button).
— Adjust the potentiometer behind the seal until the display of
the timer/counter shows 0.5x10"^ Hz or less.
— Repeat the calibration measurement described above to verify
the adjustment.
Appendix, Rubidium Timebase 9-25
- Check that the value is stable over time (>30 min). TimeView
is an excellent tool for viewing frequency stability over time.
— Attach a new calibration seal sticker so that it covers the hole
in the front panel.

Oven-Controlled Oscillators, PM9691 &
PM9692
The PM9691 is adjusted to 10 MHz ± 0.2 Hz when manufactured,
the PM9692 to 10 MHz ± 0.05 Hz, so there is no need to adjust the
frequency directly after installation.
These oscillators, like any oscillator, change frequency because of
aging. Use the table in the Operators Manual, Chapter 10, to calcu-
late when calibration is due. The complete specifications can be
found in the same manual, Chapter 11.

Table 9-1
■ Setup
- Connect the counter to the line power.
- Switch on the counter.
- Set the counter to default settings (preset).
Make the adjustment at an ambient temperature of 4-23 °C, if possi-
ble. The oscillator must have been operating continuously for 48
hours before an adjustment.
- Connect the 10 MHz OUT socket of the counter to be adjusted
(rear panel) to the Input A of the PM6681R/PM6685R.
- Set up the PM6681R/PM6685R:
“ Measuring time = 0.5 s
— 50 Q input impedance
— Frequency A measurements
■ Adjustment
The oscillator has a voltage controlled adjustment range. This range
is divided into five fixed steps set via DIP switches, and a trimmer to
fine-tune the control voltage.
Normally the range of the trimmer should be sufficient to compen-
sate for the aging that occurs during at least two years of operation.
Fine adjustment
- Adjust the trimmer to better than 10 MHz ± 0.2 Hz (PM9691)
or 10 MHz ± 0.05 Hz (PM9692), i.e. ±20 resp. ±5 in the last
two digits on the PM6681R/PM6685R display.
- If this adjustment is OK, reassemble the counter.
Coarse adjustment
Make this adjustment only if the trimmer range is insufficient to ad-
just the oscillator.
- Remove the tape from the DIP-switch.
- Adjust the trimmer to its mid position (about 12 turns from ei-
ther end position).
- Read the frequency on the PM6681R/PM6685R.
(Nominal 10.000000 MHz)
~ If the frequency is too low, set the DlP-switches to the next
higher voltage range.
— If the frequency is too high, set the DIP-switches to the
next lower voltage range.

Option PM9671B
Introduction
This optional reference output unit replaces the extra 5x10 MHz +
1x5 MHz outputs of the PM6681R and offers more frequencies
(1x0.1 MHz, 1x1 MHz, 1x5 MHz and 3x10 MHz with higher output
level (1 Vrms versus 0.6 Vrms)- The standard 10 MHz, 0.6 Vrms output
of PM668 IR is not affected.
Performance Check
Connect an oscilloscope to the outputs marked I, J, K, L, M and N and
check the frequencies (0.1, 1, 5, 10, 10 and 10 MHz), the waveform (si-
nusoidal) and the level (>1 Vrms).
Adjustments
No adjustments can be made. The output frequencies are locked to the in-
temal/extemal timebase, depending on the source selected via the front
panel or by means of a GPIB command. The default timebase source is
the built-in reference oscillator.
