Aug 29, 2016

Spectrum analyzer is of signal spectrum structure of the instrument and measurement for signal distortion, modulation, spectral purity and frequency stability degree and intermodulation distortion and signal parameters, is a multi-purpose electronic measuring instruments.

Spectrum analyzer architecture like time domain use oscilloscope, the panel cloth built many function control buttons, as the system functions, adjustment and control, the main functions of the system is displaying the spectrum characteristics of the input signal in the frequency domain. Spectrum analyzer on the basis of the signal processing methods of different, generally have two types; real-time spectrum analyzer and scanning tuned spectrum analyzer.
