I hope I'm not too off topic asking about a spectrum analyzer on this forum.
I'm looking for information on adjusting the Video Processor on a Tek 2755/494AP Spectrum analyzer.
A40 Video Processor PCB 670-8389-01
I have the service manual but adjustments for this board is not covered.
There are a few paragraphs on theory and a schematic but no explanation on how to adjust 22 potentiometers. These mostly effect band-4 leveling.
Any insights or suggestions would be appreciated.
