I was using my ADALM2000 today, and the positive power supply stopped working all of a sudden. The negative supply seems to work just fine. Is there any way I can fix this?
Did you happen to momentarily short the power supply to ground of some other voltage? If you by chance shorted the supply to a voltage beyond -5 to +5 V ( the internal supply voltages of the M2000) then you probably damaged to output circuit of the IC that drives the power supply. While the op-amp is "short circuit" protected it is not protected from voltages outside it's supply voltage. The + and - power supplies use independent drivers so one could be damaged while not affecting the other.
