How does a Spectrum Analyzer do what it does?
In this video I will be exploring the two categories of Spectrum Analyzers:
1. The Fourier Analyzer
2. The Heterodyne Analyzer
And then there is the "Hybrid" Analyzer which borrows a little from each of these.
In this series:
VIDEO #1: What a Spectrum Analyzer does. (the last one)
VIDEO #2: How it does what it does (this one)
VIDEO #3: Spectrum Analyzers Step-by-Step, a "How to" video (scheduled for release 6 July 2022)
For more information, you can read this -very- complete book:
