Introduction to Vector Network Analyzers Basics
This paper discusses why VNAs are used and how they are unique compared to other RF test equipment. We'll define S-Parameters, the fundamental VNA measurement, and how best to use them when evaluating your Device-Under-Test or DUT. We'll review various VNA calibration techniques and show how VNA user calibrations help achieve the best accuracy possible. Finally, we'll review typical VNA measurements such as swept frequency measurements, time domain measurements, and swept power measurements and how they're used and why they are important.
