parameter exists, that data are output to a Touchstone file. If
no measurement data exists, 0 (for log magnitude - angle, log
magnitude = -200 dB) is output in the corresponding field.
The following figures show the data structures of files saved in Touchstone
format.

data. This is not valid when reading the file. When
reading, the reference impedance value Z0 at option
line is always used.
