An inexpensive system for automatic measurement of microwave phase shift is described. The system requires for its construction only components that would be required if a manual system were used, plus a servo loop. The phase is controlled by controlling the reflector voltage on a klystron, which in turn controls the microwave frequency. A description is given of a prototype system that was constructed and tested. Measured results of phase shift as a function of control voltage and attenuation are presented.
