PHASE NOISE MEASUREMENT SYSTEMS

International Telemetering Conference Proceedings / October 13-15, 1981 / Bahia Hotel, San Diego, CaliforniaPhase noise is the term most widely used to describe the characteristic randomness of frequency. Automation of phase noise measurements has been developed with satisfactory results using two techniques referred to as the two-oscillator technique and the singleoscillator technique. Measurements are performed in the frequency domain using a spectrum analyzer which provides a frequency window following the phase or frequency detector. State-of-the-art systems include system modifications for cross-spectrum measurements and techniques used to improve the noise floor characteristics of the delay line FM discriminator in order to measure single sources which have very low phase noise characteristics.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
