SCPI, Command
Types
Confirmed, with query.
Example:
CALC:LIM:LOW -10, 0, 0, -10
Define the following lower and (default) upper limit line segments:
CALC:LIM:DISP ON
Show the limit line segments in the active diagram.
CALCulate<Chn>:LIMit:LOWer:FEED <stimulus offset>,<response offset>[,<trace
name>]
Generates a lower limit line using the stimulus values of a data or memory trace and specified offset
values.
<Chn>
Channel number used to identify the active trace. This trace provides the stimulus
data for the limit line unless another trace <trace_name> is specified.
<stimulus
offset>
Stimulus offset value, used to shift all imported limit line segments in horizontal
direction.
Range [def.
unit]
-1000 GHz to +1000 GHz [Hz. For distance-to-fault traces the default unit is the
length unit defined via
UNIT:LENGth
.]]
*RST value
0 Hz
<response
offset>
Response offset value, used to shift all imported limit line segments in vertical
direction.
Range [def.
unit]
-10
12
dB to +10
12
dB [dB]
*RST value
0 dB
<trace name>
Name of the selected trace as used e.g. in
CALCulate<Ch>:PARameter:SDEFine.
If no trace name is specified the
analyzer uses the active trace no. <Chn>.
SCPI,
Command
Types
Device-specific, no query.
Example:
CALC:LIM:LOW:FEED 1 GHZ, -10
Use the stimulus values of the active trace, shifted by 1 GHz to the right and
decreased by 10 dB, to create a lower limit line.
CALC:LIM:LOW:SHIF -3; CALC:LIM:CONT:SHIF 1 GHz
Shift the limit line by an additional –3 dB in vertical and by 1 GHz in horizontal
direction. If an upper limit line exists it is also shifted.
