Sniffing the Rigol's internal I2C bus

[cybernet]

So are you loading these codes with 00.01.01.00.02 and then upgrading to 00.02.01.00.03 to utilize them?

no, i just upgraded to the new fw, and applied them.

[alank2]

no, i just upgraded to the new fw, and applied them.

With a diagnostic key or generated key?  Did you find the new point and crack the new algo?  Does the 00.02.01.00.03 firmware detect a Non-A model and accept normal keys?

[AndersAnd]

for FW 00.02.01.00.03 - on a DS2000 (NON A version only !)

Code: [Select]

0x1C080    - DSEA - PROTOCOL ANALYSIS - CAN
0x1C040    - DSCA - BANDWIDTH - 300M Bandwidth (takes a reboot to show up in System Info)
0x1C020    - DSBA - (installs option, but i dont see it ?)
0x1C010    - DSAS - BANDWIDTH - 200M Bandwidth
<known codes still work - see elsewhere>

enable 0x1C0E7 -> all but 100/200M bandwidth-> DSHH

Awesome DSAS also works with older SW versions according to http://riglol.3owl.com

DS2000 device options:
first character: D = official, V = trial
DSAB - Advanced Triggers
DSAC - Decoders
DSAE - 56M Memory
DSAJ - 100MHz
DSAS - 200MHz
DSAZ - all options

i wonder if 0x1C020 is the 50Ohm option, which my hw probably doesnt support.

Can't you tell a difference in the menu if the 50 Ohm option is enabled by a key or not, even if th HW doesn't support it in HW 1 doesn't support it?

I beleive you can still use this keygen http://riglol.3owl.com and then just type DSAR DSHH instead of the usual DSAZ to enable all options on the new FW 00.02.01.00.03 for non-A DS2000, including CAN protocol analysis, 300 MHz BW (and maybe 50 ohm input option?).

Hello,
I have a DS2072 hardware 1 and can't do the update to http://www.filedropper.com/ds2302rilol and therefore no CAN.
The update procedures seems to run like it should, and then, when the scope reboots, everything is just like before. The software version did not move from 01.01.00.00.02.
I have a DS2A0000000001 serial, could that be an issue?

[alank2]

Keeping trying to update.  I had it not work, blink for just a few seconds then go solid on, but stay on the old version.  I kept at it and finally it blinked for 3-4 minutes or so and worked.

[alank2]

cybernet do you still have the CH1 200M bandwidth limit?  I can get to the 1ns timebase, but no 200M...

The bit in DSBA was accepted by the older firmware too, it would be nice to figure out what it does.  I find it interesting that they stepped around this bit, so there must be some significance to it.

Did you rename the DS2302_RILOL.GEL file to DS2000Update.GEL first? That's the only way you can load it.

But there seems to be no reason to install this custom firmware anymore after Cybernet's latest posts here with new key options for 300 MHz, CAN etc..
Just download the official firmware 00.02.01.00.03 uploaded here instead.
Then un-rar DS2000Update.GEL and load it.
After updating apply a key generated with DSAR DSHH to enable all options.

[iNoxxam]

Thanks,
I finally managed to get all the options by:
- Updating to 02.01 with the official .GEL (several times, to get it working)
- Installing the key generated with DSAR
- Installing the key generated with DSEA (for CAN)
- Installing the key generated with DSCA (for 300MHz)

My S/N is still DS2A0000000001 though. If someone finds out how to fix it I'll be interested into that.

It is now full option thanks to you... Thanks a lot!

i wonder if 0x1C020 is the 50Ohm option, which my hw probably doesnt support.

UPDATE: despite being DS2302 model, bw limit option is only NONE,20M,100M - somebody better confirm that NONE = 300M ;-)

Are LIN and USB protocol analyzers enabled too like mentioned below? Or maybe they aren't actully implemented in the firmware yet, but they have just reserved key options for it?.

Well, the firmware also shows these strings:
CAN
LIN
USB

So, how can somebody enable CAN / LIN / USB protocol analyzer at a DS2072??

cybernet has changed the enable all option from DSAR to DSHH in his post above.
But did you have to apply DSEA and DSCA afterwards too? This shouldn't be necessary if DSAR / DSHH has already enabled all options including 300 MHz and CAN.

Yup I had to. Else I would "only" have unlocked a 200MHz BW and no CAN analyzer.

Did you check that before installing the last two keys?
That's not what cybernet wrote. So you're saying DSAR to DSHH doesn't install all options anyway, but only does the same as the already known DSAZ?

Btw. have you tested this:

Yes I checked right after trying the DSAR.
Finally I uninstalled all options  (using SCPI) and tried with DSHH, this one did actually enable everything.
I did not try the BW limit in "NONE" mode, but as soon as I get my hands on a function generator be sure I will.

It looks like the 00.02.01.00.03 firmware fixes the both channels on in 1ns timebase issue.

[stormbr]

Works fine with ds2072 (non a) and hardware 2.0.

Model: DS2302
SW: 00.02.01.00.03
HW: 1.0.2.0.2
FPGA: SPU 03.01.09 / WPU 00.07.01 / CCU 12.29.00 / MCU 02.12

Note:
Need uninstall the old key with ultra sigma.
Option: DSHH + rigen 2b1
Protocol analysis CAN: ok
300MHz BW: ok
BW limit: OFF - 20M - 100M

Thanks Cybernet.

[alank2]

300MHz BW: ok

Did you test or measure this somehow?

[stormbr]

No tested this bandwith yet, but some peoples here measure easily 300mhz, in future i'll bought a pulse generator too.

And i'm waiting my dsa815tg arrive, can i generate a 300mhz signal with dsa815?

Yes, you will be able to generate 300 MHz (or anything else up to 1.5 GHz) in the Zero Span Mode.

Sure, up to 1.5 Ghz (Zero Span).  -20 to 0 dBm in 1 dB steps.

[stormbr]

Thanks for the info, great instrument !

anyone with HW 2.0 seeing if 50ohm termination is an option for the new firmware and unlocks?

[JDubU]

Works fine with ds2072 (non a) and hardware 2.0.

Model: DS2302
SW: 00.02.01.00.03
HW: 1.0.2.0.2
FPGA: SPU 03.01.09 / WPU 00.07.01 / CCU 12.29.00 / MCU 02.12

Note:
Need uninstall the old key with ultra sigma.
Option: DSHH + rigen 2b1
Protocol analysis CAN: ok
300MHz BW: ok
BW limit: OFF - 20M - 100M

If the bandwidth is 300MHz, shouldn't the BW limit menu options be:   OFF - 20MHz - 100MHz - 200MHz?
Is the bandwidth actually still 200MHZ and not 300MHz?

Never mind...
The DS2000A User's Guide, page 2-3 says:

"Enable bandwidth limit and limit the bandwidth to 20 MHz or 100 MHz (only applicable to 200 MHz and 300 MHz oscilloscopes), the high frequency components that exceed 20 MHz or 100 MHz are attenuated."

Hi,

please, can anybody give me the SCPI commands for switching the input impedance to 50 ohms and back to 1 Megaohms of the DS2072?
I done it many weeks ago and it worked fine, but now I can't remember these commands. 

Many thanks for your help.
