Default Re: HP8640B questions

Nice one, John

I can sympathise regarding your comments on serial numbers. My first 8640B (512MHz) is fitted with the wafer switch version of the deviation range vs. frequency tracking assembly (A9) and I've had to cross-reference several different versions of service manual circuit diagrams.

Much burning of midnight oil !
