Title :
A Simple Method for Precise Phase Shift Measurement
Abstract :
This paper discusses a simple method of measuring the phase shift of circuit components with very high accuracy. The method is substantially independent of loss in the circuit component. This is accomplished by using a systematic technique that eliminates errors due to the usual measuring system imperfections. The method uses a hybrid junction, a dual channel null detector circuit, and a high quality phase shift standard whose design is presented insome detail. Phase shift measurement accuracies of 1 degree have been reliably obtained on components with loss up to 40 db.
