I received my Nano V2 a few weeks ago. I put BenF 3.40 on it and watched the signal generator output for a moment, then put it away. I haven’t needed it for anything since then, but I thought I’d show it off to the folks at work. So, I upgraded to 3.51. Sadly, I can’t see an active signal now. Only a flat line at 0V (no noise when disconnected, either). I checked the signal generator output on another scope and it works fine. I downgraded to 3.41 and it appears that the input always reads a max value or something – V Avg = Vmin = Vmax = 6.84 or something on 1v/div (I can downgrade and get the exact number, if it matters). Seems like a HW problem, unless there are stored cfg files messing things up? I assume that it reads zero on 3.51 because the ground calibration get’s set to max. How can I diagnose it?
I sent this to the support email, too, but thought:
a) might get quick help here
b) someone else may run into this someday…
