1.3.9R4
1. Measurement enhancement:
a) Supported cursors for measurement
b) Supported Track plot
c) Added parameters: Positive Slope and Negative Slope
2. Display:
a) Supported to display axis label
b) Auto hide menu setting increased to 10 seconds
c) Added “Hide” button in the fast menu of channel for quickly hiding trace
3. Save/Recall:
a) Supported network storage
b) Supported to Print only grid area
c) Supported to save FFT result
d) Updated the File Manager
4. Bode
a) The maximum generator amplitude changed from 6Vp-p to 24Vp-p
b) Supported single sweep
5. Horizontal: Time Zero strategy updated – time zero changed from center display to trigger position.
6. Acquisition: Deleted some unnecessary clear operations on the history buffer
7. Updated Russian menu
8. Supported setting Cursors by virtual keypad
9. Fixed several bugs
a) Decode failure occurs on last nibble or byte
b) The “STL?” query issue in AWG function
c) If persistence is enabled, and you change the trigger setting, persistence
will be switched off
d) Decode list can't go higher than item #2
e) Decode format is reset to "binary" when recalling stored settings
f) Sequence capture does not work with serial trigger from digital channel
g) ERES 0.5-bit works for ERES(C1), but not for ERES(F1)
h) The icons for rise and fall time in the Measure Select screen are reversed
i) When switching the attenuator, the message “Zone is too small” appears
j) After shutting-down the scope and rebooting not all settings are restored
k) Bode plot abnormal when Sequence is enabled
l) SENT decode: tolerance not functional
m) SENT decode: only display CRC segment but no calculation on the CRC
checksum
n) SENT decode: The Short Serial data is NOT decoded if only 16 frames
are sent. If a 17th frame follows, the data is decoded
o) SENT decode: Changing the horizontal time/div affects the ability to
decode.
p) Save/recall: Number of digits of time stamp is not enough in the long period
q) Infinite persistence not works after switching between 8-bit and 10-bit
r) Tolerance of UART decode too strict
s) FFT max. scale is unrealistic
