Parameters
Keyword for the physical unit of the response values.
Range [def. unit] The analyzer uses dB units, irrespective of the parameter selected.
[–]
*RST value –
SCPI, Command Types
Device-specific, no query.
CALCulate<Chn>:LIMit:SEGMent<Seg>:AMPlitude:STARt <response>
Changes the start response value (i.e. the response value assigned to the start stimulus value) of a limit
line segment. A segment must be created first to enable this command (e.g
CALC:LIM:DATA
).
To define the response values of several limit line segments with a single command, use
CALCulate<Chn>:LIMit:LOWer[:DATA]
or
CALCulate<Chn>:LIMit:UPPer[:DATA]
.
<Chn>
Channel number used to identify the active trace.
<Seg>
Segment number
<response>
Response value
Range [def.
unit]
Almost no restriction for limit segments; see
Rules for Limit Line Definition.
[dB]
*RST value –
The default response values of a segment that is created by defining its stimulus
values only (e.g. by means of
CALCulate<Chn>:LIMit:CONTrol[:DATA]
), is –
20 dB.
SCPI,
Command
Types
Device-specific, with query.
Example:
CALC:LIM:DATA 1,1500000000, 2000000000,2,3
Define an upper limit line segment (segment no. 1) in the stimulus range between
1.5 GHz and 2 GHz, assigning response values of +2 dBm and +3 dBm.
:CALC:LIM:SEGM:AMPL:STAR 5; STOP 5; CALC:LIM:SEGM:TYPE LMIN
Change the segment to a lower limit line segment with a constant response value
of +5 dB.
CALC:LIM:DATA?
Query the type, the stimulus and response values of the created segment with a
single command. The response is
2,1000000,2000000,5,5
.
CALCulate<Chn>:LIMit:SEGMent<Seg>:AMPlitude:STOP <response>
Changes the stop response value (i.e. the response value assigned to the stop stimulus value) of a limit
line segment. A segment must be created first to enable this command (e.g
CALC:LIM:DATA
).
To define the response values of several limit line segments with a single command, use
CALCulate<Chn>:LIMit:LOWer[:DATA]
or
CALCulate<Chn>:LIMit:UPPer[:DATA]
.
