The spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation, spectral purity, frequency stability and intermodulation distortion. It can be used to measure some parameters of circuit systems such as amplifiers and filters. It is a multi-purpose electronic measurement instrument. It can also be called frequency domain oscilloscope, tracking oscilloscope, analytical oscilloscope, harmonic analyzer, frequency characteristic analyzer or Fourier analyzer. Modern spectrum analyzer can display the analysis results in analog or digital mode, and can analyze all radio frequency signals from VLF to submillimeter band below 1 Hz. If digital circuits and microprocessors are used inside the instrument, it has storage and calculation functions; Automatic test system can be easily formed by configuring standard interface.
