[time-nuts] HP5334B Problem?

[Flemming Larsen]

And now back to our regularly scheduled program ...

I just installed my HP equipment in a rack and now I can actually turn everything on and off with a single switch.

One HP5334B, when powered on goes through the self-test and then shows a series of dashes with no signal input. Same for the HP5334A.

The second HP5334B shows approximately 120 Hz after self-test with no input.

Is this a sign of a power supply problem? Possibly bad filter capacitors? Any suggestions what to look at first? I have a manual with schematics for the HP5334A but not for the HP5334B.

Thanks,
