For future reference, both files are attached. As blurpy said, untested.

Nice, thanks! Good to know I did the script correctly.

Hmm, just throwing out some thoughts here. I notice the SCPI command "CLREEPROM", mentioned in the first post here:
https://www.eevblog.com/forum/testgear/how-to-calibrate-siglent-spd1000x-spd3303x-spd3303x-e-series-power-supplies/

We can guess from the name that it clears the eeprom. So what's the consequence? What's stored in the eeprom? Settings probably, calibration probably, serial number possibly. Anything else?

Worst case it removes something you wont be able to get back outside the factory, and bricks the unit. Best case, it resets your settings, calibration and the weird offset.

Siglent knows if it's safe to run and whether it will fix anything, but will they tell us? Or maybe someone understands the code and can say what it does.

Thanks for testing.

I'll be providing an award!  :clap: You're the first guy that recreated part of my parser using many of my parsing messages, in Python!! (Have I told you that I hate Python? ? :)) I even had some doubts if I was looking at my parsing or another guy's parsing.  :-DD

I agree, this is probably the command that is needed and the feature that I talked about before.  :-+ Since the type of device is determined by the software, it shouldn't create a problem there.

It should delete all settings (LAN, S/N, etc.). It would be great if it deleted the calib offset. The S/N can be re-inserted via the SRLN command.

Maybe tautech could ask Siglent if this could be the way to go.

Mike wrote up the CC offset problem for me in detail last week which I forwarded to Siglent....still waiting for a reply.  :popcorn:

Thank you ;D
The many examples of output from your script that you have posted was very helpful in figuring out how to parse the firmware. I used your formatting for easy comparison!

I don't think I have heard of your hate for Python before :-DD

No luck using the CLREEPROM command, CC offset still remains!!

Best,
