As a PoC I've corrected the checksum for the FW I patched a few nights ago so that you can test.
Edit: Added patched FW with correct checksums (I think).

I haven't tried the DC bias yet, but check it out... @tv84 wins again! 🏆
KungFuJosh:
Bias also confirmed! I'm very happy the numeric keypad works for that, otherwise the +/- button moves in mV lol.

:palm: Even I am amazed! My first hint was good and the only thing missing was the checksum correction. Nice!
Show us a picture of the "CMOS Setup" upgrade screen where we can see the Hardware Version to see if it still is A07.
KungFuJosh:
Yup, hw ID is still the same.
Upon startup with the new firmware, my customizations like compensation, and measurement data were all reset. I redid them all, except for some reason short compensation fails. DCR short worked though. 🤷
I might try reflashing again and see if that changes anything. I'll also test some of my reference capacitors to see if the cal changed at all.
Anybody else want to test this fw and see if short compensation works?
Maybe somebody with a "real" 2832 can try the stock version and see if there's an issue with it or not.
Thanks,
Josh
