Spectrum analyzer is an instrument for studying the spectrum of electrical signals, which can be used to analyze the sources of interference and so on. It is a multipurpose electronic measuring instrument.
1, according to the frequency of interference signal to determine the source of interference
It is easiest to determine the source of interference based on the frequency of the signal. If the frequency bandwidth of the spectrum analyzer is narrow, it can filter out the signal with different frequency of the interference signal, and accurately measure the frequency of the interference signal, so as to judge the circuit that generates the interference signal.
2, the interference source is determined according to the bandwidth of the interference signal
Judging the bandwidth of interference signal is also an effective method to judge interference source.
