Dear list members,
I own a 3325A, a nice function generator, however it has an
intermittent fault, it resets sometimes, usually it does that during
warmup, but once in a while it also resets after a few hours. I have
this generator for several years and tried to fix the problem. I first
checked the PSU, replaced all caps, resoldered all power transistors
of the PSU, replaced all caps on the CPU/logic board, replaced the DIP
switch on the CPU board, replaced the 3 flex strips with new solid
flexcable.
I have run out of ideas, but suspect that the cause is the nano
processor ??, any ideas would be welcome,
Thanks,
Fred, PE1FBO
