On the Detection Method of weak Signal by Spectrum Analyzer
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.
