The Simple Scalar Network Analyzer

After playing around with the SynthNV signal generator/power detector discussed in the previous post I realized what a useful a tool it is for RF testing. While its a terrific tool for VHF/UHF/Microwave testing, the SynthNV has a couple of serious limitations for amateur use in the HF region - the signal generator has a minimum frequency of 35 MHz, the generated signal has a lot of harmonics and its a fairl ...
