One-end Two-port Measurement Technique for Four-port S-parameters

Abstract (in Japanese) (See Japanese page) 
(in English) One way of evaluating circuit characteristics is to measure the scattering (S)
parameters with a vector network analyzer. Since it is difficult to
set an equipotential ground on high-density boards, the authors propose
a new procedure for four-port circuit measurement, the one-end two-port measurement
technique, which does not require an equipotential ground. In order to use the one-end two-port measurement
technique,the termination condition at two ports on one end is changed with open,
short, and 50-ohm matching, and two-port S-parameters are measured at
two ports on the other end. Four-port S-parameters are calculated from
these results.
Two pairs of expressions are derived using this method.
When expressions are selected to see the effects of termination condition,
the S-parameters are correctly obtained, except for the parameters
between the far-end ports where the
termination condition is changed.
