摘　　要：频谱分析仪是一个通用、多功能的测量工具，可对频率、功率、失真、增益及噪声特性进行测量。本文简述了频谱分析仪的工作原理，并分析了频谱分析仪的分辨力、灵敏度在测量过程中的重要性，利用这些特性，来解决相近信号的辨识技巧，此外，还介绍了四种针对小信号的测试技巧。Spectrum Analyzer is a general and multifunctional measurement tool. It is capable to measure frequency, power, distortion, gain and noise features . This paper describes the working principle of spectrum analyzer, and then analyzes the importance of resolution and sensitivity of spectrum analyzer in the measurement. These features are employed to solve the identification techniques of similar signal. Moreover, the four test techniques for small signal are described.
