All,
I finally got he power supply repaired in the HP 70001A frame. I ran the system diagnostics and it quit the test with a ERR 60 RF Attenuator fault. I opened the HP 70600A module, found the programmable attenuator ( I will look up the part number when I get home).
I took the attenuator out of the module and looked at it. I took the case off of it and found the mechanical switches that switch the attenuators in and out. One of them seems to be binding up a little. I was wondering if I lubricate the switch would it fix the problem.
My question is, what is reccommended as a lube? Light machine oil, sewing machine oil, Graphite?????
Any ideas would be appreciated.
