摘要
低温接收机功率稳定度是表征低温接收机性能的主要指标之一,它反映低温接收机本身的稳定性和其对外界各种干扰因素的敏感程度。设计具有单纯环境的自动测量技术并在时域范围采用阿伦方差的方式对测量数据进行处理,计算得出低温接收机不同时间间隔的功率稳定度。该方法经过延伸后可用于测量低温、常温放大器等组部件,具有较好的实践性。
The power stability of cryogenic receiver is one of the main indexes to characterize the performance of cryogenic receiver. It reflects the stability of cryogenic receiver itself and its sensitivity to various external interference factors. In this pa per, an automatic measurement technology with shielding environment was designed, and Allan variance was used to process the measured data in the time domain. Finally, the power stability of the cryogenic receiver at different time intervals was calculated. The method can be used for measuring group components such as low temperature and normal temperature amplifiers after being extended, so it has good practicability.
