Sniffing the Rigol's internal I2C bus

I haven't tried CAN, but even RS232/SPI doesn't work as expected. Sometimes it doesn't read correct values even though signal on screen is visible and there are multiple points per bit. Also mine doesn't work on recorded data. Can someone confirm that?

And .... BIG THANKS to everyone involved in the keygen. Another success here- my poor DS2072A is now fully upgraded DS2202A. I Installed the 200 MHz option - I was too afraid to install the 300Mz one before I learn how to uninstall options.

Thanks again.

How often does this failure to decode occur? Do you have a screenshot of an example waveform where it doesn't work? And also one where you are using the same settings but it does happen to decode it correctly.

If it really fails to decode that would be bad. So far all the complaint I've read about decoding boiled down to user error. Not that I'm implying (okay yes I am but not the point ;) ) that this is user error, but if Rigol really stuffed up rs232 decoding that would be a bit sad.

I used it a couple of hours ago (1Mbps SPI) and i can confirm that it won't work sometimes when the traces are clearly visible.
After some fiddling it works again but still there is some kind of bug there.

The decoding was setup correctly.

I use the Rigol Ds2072 using zombie's 00.02.01.00.03 firmware

Slightly off topic;

I noticed that Ultra Sigma stopped being able to print my DS2102's screen a few weeks ago when my model number got corrupted to 2022.

I was eventually able to get the model to stick with 2202 after System:option:uninstall, instead of reverting back to 2022. It's now is at 2302 after the generously supplied keys.

I realize that most of you are using RUU for screen captures, but this error led me to find the following behavior in Ultra Sigma:

DS2022 -- Unable to print screen
DS2202 -- Able to print screen
DS2302 -- Unable to print screen

I believe that it didn't work as DS2302 is not an actual valid model number.

I was able to get it to work by editing the Ultra Sigma Init file in the following manner:

1. Open the Ultra Sigma Folder
2. Make a backup copy of the Init file
3. Open the Init file with word pad
4. Edit the following line to add DS2302 under 'series and model', (or any other model that you have I would expect)

DS2000 = "DS2072,DS2102,DS2202,DS2202-S,DS2102-S,DS2072-S,DS2302"

5. add under [PrintScreenSCPI]

DS2302 = ":DISPlay:DATA?"

You should now be able to print from Ultra Sigma, if before you got a communication error

6. I also added a 'DS2302.rscpi' file in the 'Instrument_Common_RIGOL_SCPI ControlPanel' folder by duplicating a DS2202 file and renaming it. This step seemed to have no effect one way or another.

Cheers to all,

Stuart

Thanks zombie28 for the IDA plugin ;)

I comfirm, 0x1C0C7 is the good option for permanent 300Mhz + all options (screenshot) Timebase : 1ns


Congratulations for all the team members as done that possible

HI...
In which model you were able to install the 300mhz?

How did you do to get the NS8H ? when i try rigup license keys.txt 0x1C0C7, windows asks to close..
