Anyone know of a troubleshooting guide for the HP 8640B?
My display reads all zero's although the generator is putting out a signal
just fine. I'd like to find a step by step guide that would lead me to the
defective component.

Thanks K. I should have said I have the manual but was hoping somewhere there
was one of those flowchart guides that leads one through to the right
component. I was hoping to avoid having to learn how all those digital
circuits work in the counter section.
I was sort of thinking maybe somewhere in HP docs there might have been such
an animal, for the HP techs to use.

This guy has the service manual for sale for $8. If you only have the
operating manual, this may give you what you need.

Check to see if the button for internal/external counter is set correctly.

Why pay anything? Most old HP manuals are available for free on the
HP/Agilent website.

Go here to search for available manuals:

Go here for both the 8640B operating and service manuals:

There is also sci.electronics.repair which currently has a thread
entitled "HP 8640B repair headaches". The OP of that thread is
apparently refurbishing them, and may be able to provide some hints.

news:sci.electronics.equipment has a lot of people who work with and
on test equipment, and don't use the repair newsgroup becasue of the
signal to noise ratio.
