Abstract :
This paper describes a new technique for measurement of vector corrected injection locking oscillator characteristics. The technique offers improved accuracy over previous measurement approaches and also allows measurement of the nonlinear time domain dynamic load-line of the oscillator. The system developed was used to measure the phase modulation characteristics of a 5.8 GHz injection locked MMIC oscillator and the results confirm the predictions made by injection locking theory.
