Example:
See MMEMory:LOAD:CORRection
MMEMory:LOAD:LIMit '<trc_name>','<file_name>'[,'<param_name>', <x_offset>,
<y_offset>, <type>]
Loads a limit line definition from a specified file and assigns it to a trace with a specified name. Limit lines
are created using the
CALCulate<Chn>:LIMit...
commands.
Limit lines can be loaded from Touchstone files (*.s<n>p, where <n> denotes the number of ports).
The optional parameters '<param_name>', <x_offset>, <y_offset>, <type> are only relevant for
Touchstone files. For *.limit files, no optional parameters can be set.
'<trc_name>'
Name of an existing trace in the active setup (string parameter). The imported
limit line is assigned to this trace, irrespective of the trace information in the limit
line file.
*RST value –
'<file_name>'
String parameter to specify the name and directory of the limit line file to be
loaded. The default extension (manual control) for limit line files is *.limit,
although other extensions are allowed. If no path is specified the analyzer
searches the current directory, to be queried with
MMEMory:CDIRectory?
. See
also note on Touchstone files above.
*RST value –
'<param_name>'
String parameter, selects an S-parameter from a Touchstone file. The parameter
must be compatible with the file type (e.g. for one-port Touchstone files *.s1p,
only the parameter name 'S11' is allowed).
*RST value 'S11' (if all optional parameters are omitted)
<x_offset>
Stimulus offset for limit lines loaded from a Touchstone file. A 1 GHz offset shifts
the limit line by 1 GHz in (positive) horizontal direction.
Range [def. unit] Depending on the sweep range of the analyzer. [Hz]
*RST value 0
<y_offset>
Response offset for limit lines loaded from a Touchstone file. A 1 dB offset shifts
the limit line by 1 dB in (positive) vertical direction.
Range [def. unit] Depending on the measured quantity. [dB]
*RST value 0
<type>
Limit line type :
LMAX – upper limit line
LMIN – lower limit line
OFF – limit line off
*RST value LMAX (if all optional parameters are omitted)
