The "Export Data - <File Type>" dialog is a standard "Save File" dialog with a number
of additional buttons to specify the export options. Many options depend on the
selected export file format ("Files of type"). The displayed controls change accordingly.
The export options are remembered when the dialog is closed.
Ask Before Overwriting
Activates a message box to be displayed before an older trace file with the same file
name and directory is overwritten.
Contents
Selects only the active trace or all traces of the active channel (including all data and
memory traces) or all traces in all channels for data export to an ASCII (
*.csv
) or Mat-
lab (
*.dat
) file.
For Touchstone file export, it is possible to export the traces in the active channel or in
all channels. See also
"Conditions for Touchstone file export"
Output Format
Selects the format of the exported raw, complex measurement values. The exported
values can be represented by the real and imaginary parts, the linear magnitude and
phase, or dB magnitude and phase; see also
Export of
is not available for Touchstone files.
Normalize with Port-Specific Impedances
For Touchstone file export only: activate this in order to renormalize according to the
port-specific reference impedances instead of a common target impedance (see
"Renormalization of S-parameters"
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.
The exported complex trace values are the values at the beginning of the trace
data flow. None of the following stages (trace mathematics, shift, time domain gate,
trace formatting and smoothing) affects the exported data. "Save" writes the raw
stimulus values (frequency/power/time, according to the sweep type) and the raw,
complex measurement points to a file..
Export of complex data is available for all trace file types.
●
Check box selected (on):
Export the values as they are displayed in the diagram,
e.g. export the dB magnitude, if trace format "dB Mag" is selected. The trace file
does not necessarily contain the full (complex) information about the trace.
For trace formats involving Cartesian diagrams (dB Mag, Real, Imag...), the stimu-
lus value and a single real response value is exported. For circular diagrams, both
the real and imaginary part of the response value is exported.
