The HP 54501A 100MHz Digitizing Oscilloscope was bought with a job lot of test equipment. In 1990 the 54501A cost $3,465 including 2 probes and Manuals.

Powered up and the 54501A works ok. This is a 4 channel digitizing oscilloscope with TV trigger, dual timebase triggering, advanced logic triggering and HP-IB programming. As I already have other Oscilloscopes, this 54501A will be resold.

The 54501A has developed a fault in the power supply. This is a complex SMPS unfortunately without a circuit diagram in the Manual.

There was nothing obviously wrong with the SMPS but it was not producing an output. Difficult to fault find without a circuit so I decided to sell the 54501A as faulty, spares or repair.
