摘要
频谱分析仪广泛应用于微波技术领域,是在频域内对信号的电平、功率、频率等参数进行测量并显示的仪器,文章从频谱分析仪的原理出发探讨了其作为测试仪器在卫星通信中的应用。
Spectrum Analyzer is widely used in the domain of microwave technique,by which can measure the level、the power and the frequence of the signal,and also the result of the measurement can be displayed by it.After further investigating the theory of spectrum analyzer,the author proposes the application of spectrum analyzer to satellite communications.
