Comparing Spectral Purity In Microwave Signal Generators
By Leonard Dickstein, Giga-tronics Incorporated
An ideal signal has no phase noise, harmonics nor spurious frequency components associated with it. Unfortunately the ideal signal does not exist in the real world, and these factors degrade the spectral purity of all real world signals to some degree. This article discusses the factors that make up spectral purity specifications to help you make more informed comparisons of microwave signal generator performance for test and measurement applications.
