Measuring the S-Parameters of a 50 to 75 Ohm impedance matching device using the Vector Network Analyzer ZVA

This document describes how the advanced calibration techniques of the ZVA Vector Network Analyzer can solve the challenges of measuring the S-Parameters on impedance matching devices. The document describes the concept and setup required to perform the calibration of the ZVA and making the measurement.

The procedure described in this application note applies to the ZVB and ZVT Vector Network Analyzers as well.
