The buttons in the "Export snp Files" section call up a dialog to store data or mem-
ory traces to a trace file of the corresponding content and file format; see
Chap-
ter 5.5.11.2, "Export Data - <File Type> dialog" , on page 310.
●
"snp Free Config..." opens a dialog to define the port assignment for the created
Touchstone (
*.s<n>p
) file. See Chapter 5.5.11.4, "Select Ports dialog" ,
on page 315.
Exporting data from the firmware simulation
When working with the firmware simulation R&S ZNXSIM , make sure to deactivate
"Simulation Noise" before exporting traces to file. Otherwise the exported results com-
prise an "artificial" random component.
Since version 3.40 of the analyzer firmware,
Simulation Noise can be activated or
deactivated from the analyzer GUI.
For a unidirectional R&S ZND (see Chapter 4.1.4.3, "R&S ZND: unidirectional vs. bidir-
ectional operation" , on page 80) S

and S
22
can be not be measured and hence an
export to
s2p
is not available.
5.5.11.1 Import Complex Data dialog
The "Import Complex Data" dialog loads a memory trace from a trace file. Trace files
are ASCII files with selectable file format. The loaded trace data is used to generate a
memory trace which is coupled to the active data trace.
Access: TRACE – [TRACE CONFIG] > "Trace Data" > "Import..."
Background information
Refer to Chapter 4.4.2, "Trace files" , on page 134.
On loading data from a trace file with several traces, the analyzer displays a dialog to
select one or more of the traces stored in the file (see
