Output Power Measurement on Noise Sources

Noise sources used for noise figure and gain measurements are typically controlled by the spectrum analyzer or noise figure meter instruments and are calibrated with their ENR value (Excess noise ratio). This application note describes a technique to perform a calibrated noise power measurement (P_hot) with spectrum analyzers and noise sources.
