Characterizing Phase Noise The term phase noise is widely used for describing short term random frequency fluctuations of a signal. Frequency stability is a measure of the degree to which an oscillator maintains the same value of frequency over a given time. This may...

Introduction Voltage controlled oscillators (VCOs) are normally designed for operation into ideal 50Ω impedance. Actual loads into which they work are seldom ideal. It is a standard industry practice to measure the variation of the frequency when the VCO output is...
