Example:
Usage:
Manual operation:
CALCulate<Chn>:LIMit:SEGMent<Seg>:AMPLitude:STARt <Response>
CALCulate<Chn>:LIMit:SEGMent<Seg>:AMPLitude:STOP <Response>
These commands change the start or the stop response values (i.e. the response val-
ues assigned to the start or stop stimulus values) of a limit line segment. A segment
must be created first to enable the commands (e.g CALCulate<Chn>:LIMit:DATA).

Tip: To define the response values of several limit line segments with a single com-
mand, use
LIMit:UPPer[:DATA].

Define upper limit lines for freqency ranges [1 GHz, 2 GHz] and
[4 GHz, 5 GHz]
:CALCulate1:LIMit1:POINts:UPPer? 'Trc1'
Query the limit lines. Returns an empty string, because limit
checking is inactive.
:CALCulate1:LIMit1:STATe ON
Activate limit checking.
:CALCulate17:LIMit1:POINts:UPPer? 'Trc1'
Returns -40,-30,-NAN(IND),-30,-40, where -NAN(IND)
is related to the center frequency 3 GHz, whose trace value is
not limited.

Virtually no restriction for limit segments
The default response values of a segment that is
created by defining its stimulus values only (e.g. by
means of CALCulate<Ch>:LIMit:CONTrol[:DATA]),
are -40 dB.
