About this document
Build Your Own Spectrum Analyser by bayman is a document available to read on EtoBox.
The document describes the design and operation of a home-built spectrum analyzer. It consists of a dual conversion superheterodyne architecture that mixes input signals between 0-50MHz with a voltage controlled oscillator to produce an intermediate frequency of 170MHz. This IF signal then passes through a crystal filter centered at 10.7MHz to determine the resolution bandwidth before being converted to a video output. The main sweep generator uses a 555 timer and integrator circuit to control the sweep rat
