Abstract
A multiport measurement system comprising a coaxial switch network and comprehensive freeware package extends the capabilities of a user's two-port automatic network analyzer and probe station to three-and four-port measurements. The coaxial switch matrix is easily constructed using inexpensive off-the-shelf components. The software includes routines for calibration, measurement, and correction, and generates normal and differential scattering and impedance parameters in a variety of standard data formats. Any in-line two-port calibration, including the multiline Thru-Reflect-Line method, may be used to correct the measurement data.
