A broken HP 33120A
<< < (5/5)

Indeed and after I have fixed all the broken pads with some "surgery", I still have the output amplifier not working  :-DD :-DD :-DD
I would say, nothing really changed  :-DD

Basically I see that I have a signal driving Q709 but no signal on the base of Q710  :-//
I am worried that the DAC is generate a too low voltage,  the SM said it should generate a 800 to 1Vpp signal but when I probe DACOUT+,DACOUT- I see only a 300mVpp signal. Now the DAC is generating an output current so it can be that I am not measuring the voltage using the correct ground.
