7.10.2.8 Saving Results
Measurement data being analyzed can be saved to floppy disks in three different ways.
(1)
T.S file ( Touchstone file)
All S-parameters of n by n for the n-port device under analysis are saved in Touchstone file
format. The extension of a file is ".snp" (n is the number of ports).The data format of S-pa-
rameter can be selected from magnitude (dB)/phase (deg) format and real part/imaginary
part format.
Saved data is arranged in the sequence shown below for each measurement frequency
(when the format is magnitude (dB)/phase (deg).
In the header of the file, "impedance 50 ɹ" is described.

CSV file
All S-parameters of n by n for the n-port device under analysis are saved in CSV file format.
The extension of a file is ".csv". The data format of S-parameter can be selected from mag-
nitude (dB)/phase (deg) format and real part/imaginary part format.
Saved data is arranged in the sequence shown below for each measurement frequency
(when the format is magnitude (dB)/phase (deg).
