analyzer is only possible if the complex trace values are available.
Export Formatted Data corresponds to a standard Save As... dialog with an additional panel to specify the
export Options. The Dec. Separator export option is not available for Matlab (*.dat) file export. Touchstone
files *.s<n>p contain either a single trace (*.s1p) or the complete set of S-parameters of an n-port and use
the point as Dec. Separator; see Trace File Formats; they are only available if complex trace values are
exported (trace formats Polar, Smith, Inverted Smith). Some of the following output options also depend
on the trace format.
• Output Format selects the format for the exported trace data. In the Re/Im format, each complex
measurement value is represented by its real and imaginary part. It is also possible to store the
linear magnitude and phase (lin Mag-Phase) or dB magnitude and phase (dB Mag-Phase) of each
value.
• Content selects only the Active Trace or All Traces of (the) Active Channel (including all data and
memory traces) for data export to an ASCII (*csv) file.
• Dec. Separator selects either the Point or the Comma (if needed to process the exported data with
an external application) as a separator for decimal numbers exported to an ASCII (*.csv) file.
• Ask to Overwrite activates a message box to be displayed before an older trace file with the same
file name and directory is overwritten.
• Customize Header... opens the Customize Header dialog to define a custom header for the
generated trace file.
Selecting an appropriate file format
Use a Touchstone file format to export a fixed number of S-parameter data traces to a file that can be
evaluated with applications such as Agilent's Microwave Design System (MDS) and Advanced Design
System (ADS). The data must be acquired in a frequency sweep.
• *.s1p files are intended for a 1-port S-parameter (the reflection coefficient S
11
) but can be used as
well to store any single S-parameter. Note that any S-parameter will be labeled S
11
in the file and
in the Select Parameter box.
• *.s2p files are intended for a complete set of 2-port S-parameters. Data export fails if the active
channel does not contain the full set of 4 traces.
