R&S ZNB/ZNBT
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
(ZNx)"
ues. For the "Version 1.1" and "Version 2.0" formats the "Data" number of digits is used
for both stimulus and data values.
Remote command:
MMEMory:STORe:TRACe:OPTion:DECimals:STIMulus
MMEMory:STORe:TRACe:OPTion:DECimals:DATA
Add Ref Impedances
For ASCII (*.csv) or Matlab (*.dat) files only: Includes the reference impedances Z
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 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
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 considered. Some trace functions (e.g. time scale, shift stimu-
lus) also affect the stimulus values.
Export of formatted data is not available for Touchstone files.
Field Separator
For ASCII (*.csv) and Matlab (*.dat) export only: defines the separator the analyzer
uses to separate different numbers in each line of the file.
Decimal Separator
For ASCII (*.csv) files only: Selects either the "Point" or the "Comma" (if needed to
process the exported data with an external application) as a separator for decimal
numbers.
