The S-parameters to be loaded must be available in Touchstone (version 1
or 2) files, which can either be
s2p
(2-port) or
s4p
(4-port) files. In case a
s4p
file is provided, the user has to take care of selecting the correct ports,
enabling the software to extract the desired set of 2-port parameters from
the Touchstone file.
