Title: HP8566B Post by: WA1GFZ on November 01, 2007, 11:43:50 AM Boss asked me to work magic on our 2 broken HP8566B spectrum analyzers. Man what a work of art inside. A good one to own.
One fixed but the other may become a queen. Anybody out there ever been under the hood of this work of art? Our soon to be crowned queen has an interesting fault that locks it up depending on information keyed in from the front panel. Has a problem making it through cal with internal 100 MHz source.

I'm looking for somebody to fix this and put my spectrum analyzer back on line. Are you interested?

I'm booked right now for home projects. but sure wanted one of those 8566 units to follow me home. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
