Wideband Measurement of Nonstandard Transmission Paths

This paper presents a means of interpreting the measurements of attenuation of non-50-ohm transmission paths when the measurements are made on a 50-ohm system. Nonstandard transmission paths are modeled as lossy lengths of transmission line. Equations are derived to calculate the transmission parameters of a nonstandard transmission path derived from its scalar S/sub 21/ parameters when measured on a 50-ohm scalar analyzer. The parameters can then be used for calculating the response of the path interfacing other impedances.
