Spectrum analyzer is a kind of multi - purpose electronic measuring instrument, which studies the spectrum structure of electrical signals.
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.
The ability of the spectrum analyzer to distinguish the frequency spacing between the two adjacent spectral lines on the display is the most important technical index of the spectrum analyzer. The resolution is related to the filter type, waveform factor, bandwidth, local oscillator stability, residual frequency modulation and sideband noise.
