I have a HP8656A signal generator. Works fine for FM and AM.
However, when using it to test a SSB receiver there is a
pronounced "warble" in the tone and it is serious enough to affect
the measurements. Any clue as to where to look for the trouble? A
friend of mine bought one at the same time and place as I did (used
equipment dealer) and his does the same thing. Any ideas or
suggestions on how to repair it? Thanks,
