3 Overview

Spectrum analyzer is a super-heterodyne receiver with display device. It consists of preselector, scanning local oscillator, mixer, middle amplifier, filter, detector, amplifier and display. It is mainly used for spectrum analysis, AND can also be used for the measurement of frequency, level, gain, attenuation, analog modulation and digital modulation, and distortion jitter, which is and indispensable instrument in communication, radio, television, radar, aerospace, and other technology areas.
