8590A Spectrum Analyzer
Hi Michael
Thanks for your quick response. Do you have any
further information on the mixer (schematics and/or type),
so I am able to replace it myself.
Best regards

Hi folks
I have got an old 8590A Spectrum Analyzer from my company,
unfurtunately with a defect. The amplitude levels shown on the screen
is app. 10 dB below the actual applied input level, so the attenuator
or input circuit apparently has a defect.
Does any one have a service manual, diagrams etc. of this model ?
Thanks in advance

It is probably a damaged mixer module. We had several fail in our
8590As over several years of heavy use. There is a maximum power level
marked by the input connector, and if you exceed it, you can damage, or
completely destroy the mixer.
