repairing a HP 3325A

So, I'm sure you've tried adjusting the amplitude while connected to Sync. But did you try it while connected to the main output? By default, it starts set to 1mV P-P, which is damn near impossible to see.

Set the amplitude to 1mV, then switch to 5V, and you should definitely hear a relay click. The click is a bit delayed, so don't worry, the button clunk won't obscure it.

did you enable the output ?
the 3325 output is off by default.... you need to press the button to enable the output.

Are you sure? Mine turns on set to sine, 1mV p-p, 0V offset... :o

carbon dude oxide:
I have just tested it and yes it does automaticaly set it to 1mV p-p by default :)

Thank you very much for pointing out that i am the one at fault ^.^

Time to tackle te PSU i got aswell which i know is broken :P (one of the pots has died and the front panel terminals are very crusty)
