Channel number used to identify the active trace
Usage: Event
Manual operation: See "Clear Test" on page 517
CALCulate<Chn>:LIMit:CONTrol[:DATA] <FreqPowTime>, <FreqPowTime>...
Defines the stimulus values of the limit line and/or creates new limit line segments. See
also
Chapter 4.4.1.1, "Rules for Limit Line Definition" , on page 129.
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
.

Channel number used to identify the active trace
Parameters:
<FreqPowTime> Default unit: NN
<FreqPowTime> Pair(s) of frequency, power or time values, to be defined in
accordance with the sweep type (
[SENSe<Ch>:]SWEep:TYPE
). See also Chapter 4.4.1.1, "Rules for Limit Line Definition" ,
on page 129.
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.
Default unit: NN
