It was time to upgrade my repair bench with a new piece of equipment. I bought this HP 8656B (w/ Opt. 001) to replace my HP 8640 and Heathkit SG-8 for customer repairs. This is a very nice signal generator and easier to use than my older models. I placed it under my spectrum analyzer since both units are used to adjust radios for optimum performance.
If you have a shortwave radio or ham radio that you would like repaired, then please send me a message.
