MMEMory:LOAD:TRACe '<trc name>','<file name>'[,'<parameter name/trace
identifier>']
Loads trace data from a specified trace file and assigns it to a trace with a specified name. Traces are
created using the CALCulate<Ch>:PARameter:SDEFine... command.
Renormalization rules for imported Touchstone files
In automatic renormalization mode (MMEMory:SETTings:RENorm:MODE AUTO), renormalization is
enabled. In explicit renormalization mode (MMEMory:SETTings:RENorm:MODE EXPLicit),
renormalization is controlled by MMEMory:SETTings:RENorm:STATe.
The analyzer uses the reference impedance of the physical ports as a target impedance; the
MMEMory:SETTings:RENorm:RIMPedance setting is ignored.
ASCII file data (*.csv, *.dat) are never renormalized.
'<trc name>'
Name of an existing data trace in the active setup (string parameter). The trace
data is loaded into a memory trace associated with the specified data trace. If one
or more memory traces are already associated with the specified data trace, the
last generated memory trace is overwritten.
'<file name>'
String parameter to specify the name and directory of the trace file to be loaded.
Several file formats for trace files are supported. If no path is specified the
analyzer searches the current directory, to be queried with
MMEMory:CDIRectory?.
The file extensions *.s<n>p, *.csv, and *.dat for Touchstone, ASCII, and Matlab
files are mandatory.
'<parameter
name/trace
identifier>'
Optional string parameter: For imported Touchstone files for more than one port
(*.s2p, *.s3p, *.s4p), the parameter denotes the imported S-parameter ('S11',
'S12', ...). For ASCII (*.csv) and Matlab (*dat) files, the parameter identifies a
particular trace in the file (case sensitive). If the parameter is omitted, the first trace
in the specified file is imported.

Example:
Assume that the current setup contains a trace named Trc1.
MMEM:STOR:TRAC 'TRC1', 'C:\Program
Files\Rohde&Schwarz\Network Analyzer\Traces\Trc1.s1p'
Store the current trace data of Trc1 to a trace file.
MMEM:LOAD:TRAC 'TRC1', 'C:\Program
Files\Rohde&Schwarz\Network Analyzer\Traces\Trc1.s1p'
Load the previously created trace file and create a memory
trace assigned to Trc1.
CALC:PAR:DEF:SGR 1,2
Create four traces to measure the two-port S-parameters S
11
, S

21
, S

. The
traces are not displayed.
MMEM:STOR:TRAC 'TRC1', 'C:\Program
Files\Rohde&Schwarz\Network Analyzer\Traces\Trc1.s2p'
Store the four S-parameter traces to a two-port Touchstone
