Re: HP8640B Signal Generator
Good work! Does the rotary vernier adjust the output power seen on the RF Level meter? You must be fairly close to having a fully working HP8640!
There's some interesting info about the levelling system in the HP app note attached below. This only covers operation up to about 512MHz and I guess things become more challenging if the generator has the 1024MHz frequency doubler option fitted.
