The Multi-State Two-port: An Alternative Transfer Standard

In a companion paper [1] the proposed use of a "stable solid state programmable impedance generator" as a calibration transfer and verification standard, for vector network analyzers, (VNA) has been suggested. An obvious requirement is that the multi-state device provide a high degree of stability and repeatability. This paper describes a series of preliminary tests, using the NIST six-port systems, to evaluate the parameters of interest. The application of this device in connector evaluation is also reported.
