I am looking for the Vol 1 and Vol 2 service manuals for the Datron Wavetek 4920 AVMS. I have the ones for the 4920M but there are differences of note.
Hard copy or soft copy, I can digitize hard copy or arrange to pay for it.
Thank you.
The only thing I found was the AVMS spec sheet here:https://bama.edebris.com/manuals/ (https://bama.edebris.com/manuals/)
I have the user manual for the 4920, which includes performance verification and adjustment procedures.
Finally found the 4920 schematics, amended into a 4920M Vol 2 manual to create a "super" Vol 2. Some info on the 4950. Also found user and service on the 4922 WB module:
