One possible substitute for a Spectrum Analyzer's "Tracking Generator" #ubitx

I got an email from a trusted friend this morning with some very interesting information for those who have spectrum analyzers that do not have tracking generators, or the new versions of inexpensive VNA's like Ashhar's "Antuino" or the NanoVNA which have sweep functions but I'm not sure exactly how they work in this respect.
