Description
technical field [0001] The invention relates to the technical field of low-temperature amplifier testing, in particular to a low-temperature amplifier power stability testing system and a testing method thereof. Background technique [0002] The cryogenic amplifier is one of the core components of the cryogenic receiver, which determines the success or failure of the entire receiving system. Since cryogenic receivers are mainly used in astronomical observations and military reconnaissance radars that require extremely high sensitivity, the stability of the cryogenic amplifier is related to the overall performance of the cryogenic receiver. At present, the power stability test of cryogenic amplifiers usually uses manual testing, which requires long-term measurement and manual data recording. When the amount of data is large and the measurement accuracy is high, problems such as misoperation and misrecording are prone to occur, affecting measurement efficiency and Reliability...
