Ask before Overwriting
Activates a message box to be displayed before an older trace file with the same file
name and directory is overwritten.
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. See
Export of complex data is available for all trace file types.
●
Check box selected (on):
Export the the values as they are displayed in the diagram,
e.g. export the logarithmic 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 stimulus
value and a single real response value is exported. For circular diagrams, both the
real and imaginary part of the response value is exported.
The trace values are the fully processed values as they appear in the diagram area.
They correspond to the results in the marker info field. All possible stages of the trace
data flow (e.g. trace formats, trace mathematics, time domain transform, shift,
smoothing) are taken into account. Some trace functions (e.g. time scale, shift stim-
ulus) also affect the stimulus values.
Export of formatted data is not available for Touchstone files.
Output Format
For Touchstone file export only: Selects the 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 formatted data is not available for Touchstone files.
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 Matlab
(
*.dat
) file.
For Touchstone file export, it is possible to export the traces in the active channel or in
all channels. See also
