摘　　要：频谱仪是装备日常维护保养中最常用的仪器之一。如果被测信号较弱,则频谱仪很难有效检测相关信号。基于此,本文简要介绍了频谱仪的构造原理,提出了四种测试微弱信号的设置方法,并通过实际测试验证,有效解决了检测微弱信号“看不见、测不准”的问题,以供相关研究参考。Spectrum analyzer is one of instruments commonly used in equipment daily maintenance.When the detected signal is weak,it will be difficult for the spectrum analyzer to detect the signal effectively.In this paper,the construction principle of the spectrum analyzer is briefly introduced,and four kinds of setting methods for detecting weak signal are proposed.Through the actual test verification,the problem that the weak signal can not be detected and the detection is effectively solved,providing reference for relevant personnel.
