Re: Advice on HP Function Generator Repair

Not having seen a picture of the function generator, I'm presuming you're
using an external oscilloscope to look at the FG's output.

Just a question: Have you been able to verify that the strange waveforms are
actually coming from the function generator itself, rather than an artifact
of... say, the oscilloscope probe and/or the oscilloscope itself not being
able to handle incoming frequencies that high? Just don't want you to waste
time trying to fix something that may not actually be broken. :)

If it is definitely coming from the function generator, then I'd agree with
the previous posters: replace the electrolytic capacitors. They're over 20
years old now.
