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
