Export TOUCHSTONE File
Exchange Import/ExportExportTOUCHSTONE
This dialog box offers TOUCHSTONE file compatible export for the S-parameters.
The extensions of the exported files names are specified by ”.sNp”
where N stands for the number of ports in your model (e.g. ”.s3p”).
The S-Parameter in the resulting TOUCHSTONE file will correspond to the
systems port modes in ascending order. For an example with two ports,
where the first port (named port 1) has 2 modes and the other port (named
port 3) and has one mode, this would mean: 1(1), 1(2), 3(1).
The TOUCHSTONE export requires the following:
All S-parameters (the full S-matrix) must be calculated. If, for a
loss-free two port structure, not all S-parameters are available, the
export option will try to derive the missing results from the existing
ones by using some analytic matrix properties. For arbitrary examples
it is possible to export an incomplete S-matrix by excluding
all ports that were not excited.
The TOUCHSTONE file contains a fixed reference impedance. During the
export process, usually the S-parameters will be automatically normalized
to this impedance, if necessary. In some rare cases, it may also be useful
to export the S-parameters as they are (without renormalizing), but nevertheless
specifying a reference impedance in the TOUCHSTONE file.
In addition, you can narrow the frequency range exported to the TOUCHSTONE
file to the range of interest. This reduces the size of the exported file
and thus helps to save disk space.
Impedance
You need to enter the reference impedance for
the TOUCHSTONE file into this field.
Renorm S-parameter
If this option is checked, the S-parameters
will be automatically renormalized to the specified reference impedance
during the export process.
Use calculated frequency
range and sampling
If activated, the full frequency range and the
original sampling of the S-parameter data is exported to the TOUCHSTONE
file. If not activated, the Export
Frequency Range dialog box is opened enabling you to narrow the frequency
range or change the sampling of the exported data.
Use AR-Filter results
Export the S-parameter results provided by the
AR-Filter
analysis. This option is only visible if there are any AR-filter results.
Save
Exports your current S-matrix to a TOUCHSTONE
file.
Cancel
Closes this dialog box without performing any
further action.
