CALCulate<Chn>:LIMit:UPPer:FEED
Generates an upper 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]
*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:UPP:FEED 1 GHZ, 10
Use the stimulus values of the active trace, shifted by 1 GHz to the right and
increased by 10 dB, to create an upper limit line.
CALC:LIM:UPP: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 a lower limit line exists it is also shifted.
CALCulate<Chn>:LIMit:UPPer:SHIFt <numeric_value>
Shifts all lower and upper limit line segments assigned to the active trace in vertical direction.
This command is identical with CALCulate<Chn>:LIMit:LOWer:SHIFt.
<Chn>
Channel number used to identify the active trace.
<numeric_value>
Response offset value for all limit line segments.
Range [def. unit]
Almost no restriction for limit segments; see Rules for Limit Line Definition.
