On-Line Accuracy Assessment for the Dual Six-Port ANA: Extension to Nonmating Connectors

Abstract

A technique is described for calibrating a dual six-port or four-port automatic network analyzer (ANA) so that the scattering parameters of two-port devices having any combination of connectors can be measured. The technique is a generalization of the "thru-reflect-line" (TRL) calibration technique in which the thru is replaced with a second length of precision transmission line. Expressions for errors associated with the second line are derived.
