I’ve run into a bug, where the DSO Nano displays (part of) the correct signal, but at an inflated voltage on the display (and with the “V avg” measure).
Test signal on 1V/div is 2.0v avg and displays correctly. Test signal on 2V/div is off the screen and 25.92V avg displayed. ???
Measuring my signal generator’s 5.1V output shows 81v avg.
Measuring small signals at 1V/div is correct.
