Compatibility with other instruments
The VNAs of the R&S
ZNx and R&S
ZVx families use the same file format. Limit line
files can be interchanged without restriction.

File format for ripple limits
The analyzer uses a simple ASCII format to export ripple limits. By default, the ripple
limit file has the extension
*.ripple
and is stored in the directory shown in the "Save
Ripple Limits" and "Recall Ripple Limits" dialogs. The file starts with a preamble con-
taining the channel and trace name and the header of the range list. The following lines
contain the entries of all editable columns of the list.

Trace files
The R&S
ZND can store one or several data or memory traces to a file or load a mem-
ory trace from a file.
Trace files are ASCII files with selectable file format. The analyzer provides several
types of trace files:
●
Touchstone (
*.s<n>p
) files
●
ASCII ("*.csv") files
●
Matlab ("*.dat") files are ASCII files which can be imported and processed in Mat-
lab.
The trace file formats complement each other; see
