Characteristics and Accuracy of a Fully Corrected Four-port Vector Network Analyzer

A new, fully corrected, four ports-parameter test system has been developed and evaluated. In this system, all sixteen s-parameters are accurately measured by a fully vector corrected system. The new test system is compared to conventional methods of measuring 4-port s-parameters, and measurement examples are shown. Accuracy of measurements with the new system is compared to measurements made conventionally. The importance of minimizing cross-talk between ports in the new test set is described, and the high level of performance achieved with the system is defined.
