The frequency stability of my HP3312A function generator is poor, very
annoying for any practical use. I am trying to determine whether that
behavior is fairly normal for function generators, or my particular
unit has got a problem.

What is your experience on function generators frequency stability?

Thanks & 73

it depends on the clock source;
some generators use better,ovenized crystal timebases.
The HP synthesizers had an option for high stability timebases,ISTR.
or you can feed in an external timebase.
At TEK,I used to feed a HP3336 with the output from my WWVB receiver.
