HP-8640b opt.323 stability question

I have an HP-8640b opt.323 signal generator which
seems to be working ok, except the final two digits
on the display keep fluctuating, even after 3 hours
warm up. Is this normal, or do I need to check out
the service manual.

Thanks in advance.

cheers, Paul - VA7NT email:
