Re: Defective Power supply in HP8711a Network Analyser.

Uhmm,
Cesar Valenti is the nickname of the Agilent employee who is in this
group.
You should search for him here and you can ask him about the
schematic.
The only problem (I repeat myself), is that he can't scan all the
schematic pages, you should at least identify the block where the
problem is.

I imagine you checked the monitor board too, do you?

One more suggestion, some switching PSUs have the shortcircuit
protection with a very long time retention function (when you remove
the power supply too), do you turn off the instrument for 4/5 minutes
after any test?


Have a nice day, good luck with your issue.
