8350B w/83590A repair advice


 

Hi group. Have this coming and see quite a few references to (at least) the 8350B.
Anyone have interest in helping me repair it?

Symptom is very low output below 10GHz and next to nothing above that.
No doubt problem is with the plug in. Maybe the power amp module. (?)

1st to check: AUX OUT as this is a sample of the YIG, 2 to 7 GHz I believe. (0 dBm)

The manual (pdf) from Keysight isn't good at all. Bought one off e-scam. We'll see.

Those plug-ins look packed tight!

Cheers!
