CALCulate<Chn>:LIMit:CONTrol[:DATA] <StartStim>, <StopStim>[, ...]
Defines the stimulus values of the limit line and/or creates new limit line segments. See
also Chapter 5.4.1.1, "Rules for Limit Line Definition", on page 135.
Rules for creating segments
The following rules apply to an active trace with n existing limit line segments:
●
An odd number of values is rejected; an error message -109,"Missing parameter..."
is generated.
●
An even number of 2*k values updates or generates k limit line segments.
●
For n > k the stimulus values of all existing limit line segments no. 1 to k are upda-
ted, the existing limit line segments no. k+1, ..., n are deleted.
●
For n < k the stimulus values of the limit line segments no. 1 to n are updated, the
limit line segments n+1, ,..., k are generated with default response values (see
CALCulate<Chn>:LIMit:UPPer[:DATA], CALCulate<Chn>:LIMit:
LOWer[:DATA]).
Note: The generated segments are upper or lower limit line segments, depending on
the CALCulate<Chn>:LIMit:SEGMent<Seg>:TYPE setting.
CALCulate<Ch>:LIMit:CONTrol[:DATA] does not overwrite the type setting.
Tip: To define additional new limit line segments without overwriting the old segments
use CALCulate<Chn>:LIMit:DATA.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<StartStim>
<StopStim> Pairs of stimulus values, each pair confining a limit line segment.
See also Chapter 5.4.1.1, "Rules for Limit Line Definition",
on page 135.
If not specified, the units are adjusted to the sweep type of the
active channel ([SENSe<Ch>:]SWEep:TYPE).
Range: Virtually no restriction for limit segments.
*RST: A segment that is created implicitly, e.g. by means
of CALCulate<Ch>:LIMit:UPPer[:DATA] or CALCu-
late<Ch>:LIMit:LOWer[:DATA,], covers the maxi-
mum sweep range of the analyzer.
Example:
*RST; :CALC:LIM:CONT 1 GHZ, 2 GHZ
Select a lin. frequency sweep (default) and define an upper limit
line segment in the stimulus range between 1 GHz and 2 GHz,
using default response values (–40 dB).
CALC:LIM:DISP ON
Show the limit line segment in the active diagram.
Manual operation: See "Segment List" on page 348
