I apologize if this should be in the tech instrument section but since it has to do with my recent alignment adventures with post war RCA TVs, I thought I might get better viewership and specific use feedback in this section.
I'll be getting back to the RCA alignment next week so I'm revving up to start that torture again. Meanwhile, I was able to pick up another HP Sweep Generator to see if it could be used in future alignments. It is an HP8620C that has the plug in RF module.
I have the service manual and it looks like it does have some internal marker capability but I'll need to play with it first. I think this was the last of the HP generators without a digital frequency readout. Manufacture date 1975. The basic sweep unit was a few hundred dollars back then but the RF module was insanely priced at over $13,000! The coaxial lines in the module are shielded with solid metal tubes. There are several YT videos on maintenance and repair so I'll be watching them. If anyone has any experience with this instrument, please let me know. As a sweeper/alignment noobie I think it can be used for TV IF alignments but I'm not sure.
