Spectrum analyzer is divided into real-time analysis and sweep type two categories. The former can get all the required spectral information in the real time of the signal under test and analyze and display the analysis results; the latter needs repeated sampling process to complete the repeated information analysis. Real-time spectrum analyzer is mainly used for non-repetitive, short duration signal analysis. The non-real-time spectrum analyzer is mainly used for the analysis of a certain continuous radio frequency signal and periodic signal from the audio up to the sub-millimeter band.
