Absolute Magnitude and Phase Calibrations

Abstract

In VNA measurements, the magnitude and phase of a transmitted or reflected wave are measured relative to that of the incident wave. VNA measurements are made a single frequency at a time and each frequency component is acquired relative to the internally generated excitation signal at that frequency. As a result, traditional VNA measurements cannot gie us information on the phase relationships between frequency components since each measurements of a collection of known, linear artifacts, as discussed in Section 4.2. Measurements such as these, based on single-frequency acquisition and realtive calirbations, are useful for finding the linear response of systems such as electronically passive networks.
