摘要
简述了利用频谱仪测量卫星信标频率的原理和方法程序。给出了频谱仪测量射频信号频率的误差模型,分析了频谱仪测量频率误差因素。讨论了用频谱仪测量信号频率应注意的问题。最后,给出利用中电41所AV4036G频谱仪测量130°E星Ka波段右旋园极化信标频率的测量结果,并计算了频率测量误差。
In this paper, measuring principle and method of satellite beacon frequencies are described simply using spectrum analyzer. Error model of spectrum analyzer measurement RF signal frequency is given, and error factors of spectrum analyzer measurement frequency are analyzed. Questions needing attention of signal frequency measurement are discussed using spectrum analyzer. At fast, test result of 130°E satellite Right Hand Circular polarization beacon frequency is given by CETC 41,AV4036 G and frequency measurement error is calculated.
