Abstract : Measurement techniques for characterizing the noise output of microwave noise generators are described. The aim of these measurements is to formulate a quantitative basis for the comparison, selection and utilization of microwave noise generators. Three measurements, namely: the power density spectrum, the autocorrelation function, and the probability density function (PDF) are discussed. Experimental results for a crossed-field noise generator are shown. A computer program which was formulated to determine the statistics of the measured PDF and permit comparison of test results with a 'normal' distribution is also discussed. Experimental results and analysis of two different noise spectra are also included to illustrate the utility of the noise measurement techniques. (Author)
