Hi,
we have a 8116A that has lost (most of) the output signal since a couple of months. Agilent doesn't repair these oldies anymore, so I'm trying to find out if there's a chance to solve the problem by myself.
The signal is not completely gone, with a scoop set to 10mV/div I can still see a ~20mV signal, with the correct frequency & waveform, but neither the 'disable' button or increasing the signal strength have any effect, so my guess is it's either the Output Disable function or a driver circuit. The TRIG OUTPUT signal is Ok btw.
With a schematic I could probably find out where the problem lies, but a search brought no solution there, so my question is: has anyone seen this before, and does he or she know where I could look inside the instrument (or better yet, what part it could be)?
Thanks for all answers.
Theo
