NOTE
In the 2-port matching circuit embedding or the 2-port network de-embedding feature, if
the normalized impedance value specified in the user file (2-port Touchstone data file) is
different from the port reference impedance setting value of the analyzer, it is
automatically converted to adapt to the analyzer setting.
When a 2-port Touchstone data file is read in, data for up to 3202 frequency points are read
in using interpolation according to the measurement frequency point setting of the
analyzer. If the number of frequency points in the file is greater than 3202, excess data are
ignored.
For a network defined in the user file, it is assumed that port 1 is connected to the test port
and port 2 is connected to the DUT.
