A technique has been developed for calibrating the operating noise-temperature of low-noise earth station receiving systems. the technique, which consists of switching the maser input between the antenna and a microwave ambient termination, has been used on several antenna cone configurations for a deep space communications system. the details of the calibration technique, error analysis, and programming are presented.
