#43 - HP 8590A spectrum analyzer repair - part 1 of 3
A good old HP 8590A spectrum analyzer, which was picked up from eBay for parts or repair. It turned out to have a bad mixer in the first converter. A matched pair of schottky diodes was dead. A replacement was found and installed. The analyzer seems to be back in business. Perhaps, it will need some adjustments though.
