first response value of second trace. HZ / KHZ / MHZ / GHZ allowed for imported
files. The analyzer always uses HZ for exported data. second response value of

The trace data is arranged as described in the header. Different values are separated
by semicolons, commas or other characters, depending on the selected "Decimal Sep-
arator" in the "Export ... Data" dialogs. A semicolon is inserted before the end of each
line.
The stimulus values are arranged in ascending order.

Finding the Best File Format
The file format depends on how you want to use the exported data.
Use a
Touchstone
file format to export single-ended 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), and to convert mixed mode parameters
back to single-ended parameters. The data must be acquired in a frequency sweep.
Note the
"Conditions for Touchstone file export"
Use the
ASCII (*.csv)
format if you want to do one of the following:
●
Import the created file into a spreadsheet application such as Microsoft Excel.
●
Export an arbitrary number of traces, multiple traces with the same parameter or
memory traces.
●
Export traces acquired in a CW sweep.
●
Use export options.
Use the
Matlab (
*.dat
)
format if you want to import and process the trace data in
Matlab.
