CALCulate<Chn>:LIMit...
This subsystem defines the limit lines and controls the limit check.
CALCulate<Chn>:LIMit:CONTrol[:DATA] <start>,<stop>{,<start>,<stop>}
Defines the stimulus values of the limit line and/or creates new limit line segments.
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 updated, 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]).
The generated segments are upper or lower limit line segments, depending on the
CALCulate<Chn>:LIMit:SEGMent<Seg>:TYPE setting.
CALCulate<Chn>:LIMit:CONTrol[:DATA] does not overwrite the type setting.
To define additional new limit line segments without overwriting the old segments use
CALCulate<Chn>:LIMit:DATA.
<Chn>
Channel number used to identify the active trace.
<start>,
<stop>
Pair(s) of frequency values.
Range [def.
unit]
Almost no restriction for limit segments; see Rules for Limit Line Definition. [Hz. For
distance-to-fault traces the default unit is the length unit defined via UNIT:LENGth.]
*RST value –
A segment that is created implicitly, e.g. by means of
CALCulate<Chn>:LIMit:UPPer[:DATA] or
CALCulate<Chn>:LIMit:LOWer[:DATA,], covers the maximum sweep range of
the analyzer.

Command
Types
Confirmed, with query.
Example:
*RST; CALC:LIM:CONT 1 GHZ, 2 GHZ
Define an upper limit line segment in the stimulus range between 1 GHz and 2 GHz,
using default response values.
CALC:LIM:DISP ON
Show the limit line segment in the active diagram.
