Hi folks. I've been a fan of tuners, receivers, and radios in general since I was a boy. I'm interested in building a little test stand for testing mostly vintage tuners, and for doing a little design work too.
Before I could collect any test equipment of my own, my buddy lent me a Keysight FieldFox. This is a portable network analyzer/tester for field work. This model supports vector S11 and scalar S21 measurements. Vector S11 is return loss magnitude and phase measurement of input ports. Scalar S21 is gain magnitude.
The S11 test can be used to measure return loss or VSWR on passive networks including antennas. I plan to test the return loss of various antennae I have laying around. The S21 tests can be used to sweep devices (amplifiers, filters, etc) from low VHF into microwave.
There have been some great postings here recently about building high performance antenna for FM, baluns for matching test equipment to tuners, etc. If someone has used a FieldFox or a network analyzer for antenna or FM tuner work. I'd love to hear about the kinds of measurements and analysis that can be done.
