Sweep-tuned spectrum analyzer

Mar. 09, 2017

The sweep-tuned spectrum analyzer is frequently-used. Its basic structure is similar with the superheterodyne receiver. The working principle of the sweep-tuned spectrum analyzer is adding the signal to the mixed wave device through the attenuator, then the under clocking IF signal through reamplifying, smoothing, detection are sent to the vertical direction board of the CRT.
