Spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is a multipurpose electronic measuring instrument.
It is used to measure signal parameters such as signal distortion, modulation, spectrum purity, and so on.
Spectrum analyzer is a necessary means to measure radio signals, and is a common tool for research and development, production and inspection of electronic products. Therefore, the radio frequency multimeter which is widely used is called "engineer".
