Note: Limit lines can be loaded from Touchstone files (*.s<n>p, where <n> denotes the
number of ports). The optional parameters '<TouchstoneFile>',
<StimulusOffset>, <ResponseOffset>, <LimLineType> are only relevant for
Touchstone files. For *.limit files, no optional parameters can be set.
Setting parameters:
<TraceName> Name of an existing trace in the active recall set (string parame-
ter). The imported limit line is assigned to this trace, irrespective
of the trace information in the limit line file.
<LimLineFile> 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.
<TouchstoneFile> 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: 'S11' (if all optional parameters are omitted)
<StimulusOffset> 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: Depending on the sweep range of the analyzer.
*RST: 0
Default unit: NN
<ResponseOffset> Response offset for limit lines loaded from a Touchstone file. A
1 dB offset shifts the limit line by 1 dB in (positive) vertical direc-
tion.
Range: Depending on the measured quantity.
*RST: 0
Default unit: NN
<LimLineType> LMIN | LMAX | OFF
Limit line type :
LMAX - upper limit line
LMIN - lower limit line
OFF - limit line off
*RST: LMAX (if all optional parameters are omitted)
