CALCulate<Chn>:LIMit:SEGMent<Seg>:STIMulus:STOP
<StimVal>
These commands change the start and stop stimulus values (i.e. the smallest and the
largest stimulus values) of a limit line segment. A segment must be created first to
enable the commands (e.g
ter 4.4.1.1, "Rules for limit line definition"
Tip:
To define the stimulus values of several limit line segments with a single com-
CALCulate<Chn>:LIMit:CONTrol[:DATA]
.
Suffix:
<Chn>
.
Channel number used to identify the active trace
<Seg>
Segment number
Parameters:
<StimVal>
Stimulus value confining the limit line segment.
If specified, the unit of a stimulus value must in accordance with
the sweep type of the active channel (
Hz
for frequency sweeps,
dBm
for
power sweeps, and
s
for time sweeps. For CW mode sweeps,
stimulus values are dimensionless.
Default unit: NN
Example:
CALC:LIM:DATA 1,1500000000, 2000000000,2,3
Define an upper limit line segment (segment no. 1) in the stimu-
lus range between 1.5 GHz and 2 GHz, assigning response val-
ues of +2 dB and +3 dB.
CALC:LIM:SEGM:STIM:STAR 1GHZ; STOP 2 GHZ; :
CALC:LIM:SEGM:TYPE LMIN
Change the segment to a lower limit line segment with a stimu-
lus range between 1 GHz and 2 GHz.
CALC:LIM:DATA?
Query the type, the stimulus and response values of the created
segment with a single command. The response is
2,1000000000,2000000000,2,3.
Manual operation:
See
CALCulate<Chn>:LIMit:SEGMent<Seg>:TYPE
<LimLineType>
Selects the limit line type for a limit line segment. This can be done before or after
defining the stimulus and response values of the segment, however, a segment must
be created first to enable this command (e.g
CALC:LIM:DATA
).
Note:
The type command overwrites the
and is overwritten by them. It is not affected by the other commands in the
CALCulate<Chn>:LIMit...
subsystem defining stimulus and response values of
limit lines.
