Normalize with Port-Specific Impedances
For Touchstone file export only. If checked, the firmware renormalizes the exported S-
parameters according to the port-specific reference impedances instead of a common
target impedance of 50
Ω
(see
"Renormalization of S-parameters"
Note
however, that during import the firmware always assumes a common reference
impedance of 50
Ω
.
Balanced Params
For Touchstone file export only: activates/deactivates the export of balanced (and
mixed-mode) S-parameters.
Note:
●
Please consider
"Conditions for Touchstone file export"
if only one port of a balanced port is selected, then the export fails.
●
In contrast to single-ended S-parameters, balanced S-parameters are always nor-
malized.
Remote command:

Decimal Places
Opens a dialog that allows you to specify the number of decimal places for stimulus
and data values in all supported trace data files (Touchstone, ASCII, MatLab).
The allowed range is 1 (minimum precision) to 15 (maximum precision). "Reset Deci-
mal Places" resets these numbers to their respective defaults, which is 15 in both
cases.
Note:
In the current implementation of the Touchstone file export, only the "Version 1.1
file format supports independent settings for stimulus and data val-
ues. For the "Version 1.1" and "Version 2.0" formats the "Data" number of digits is used
for both stimulus and data values.
Add Ref Impedances
For ASCII (
*.csv
) or Matlab (
*.dat
) files only: Includes the reference impedances Z
0
for all analyzer ports in the file header.
Formatted Values
For ASCII (
*.csv
) or Matlab (
*.dat
) files only: Selects the format for the exported
trace data.
●
Check box cleared (off):
Export the raw complex (unformatted) measurement val-
ues, represented by the real and imaginary parts, the linear magnitude and phase,
or dB magnitude and phase.
