ZVA/ZVB/ZVT CALCulate
1145.1084.12 6.75 E-6
<Ch/Tr> Channel number used to identify the active trace.
<numeric_value> Pair(s) of response values.
Range [def. unit] Almost no restriction for limit segments; see Rules for Limit Line Definition.
[dB]
*RST value –
The response value of a segment that is created implicitly, e.g. an lower
limit line segment, is –20 dB.
SCPI, Command
Types
Confirmed, with query.
Example:
CALC:LIM:UPP -10, 0, 0, -10
Define the following upper and (default) lower limit line segments:
CALC:LIM:DISP ON
Show the limit line segments in the active diagram.
CALCulate<Ch/Tr>:LIMit:UPPer:FEED
Generates an upper limit line using the stimulus values of a data or memory trace and specified offset
values.
<Ch/Tr>
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. <Ch/Tr>.
SCPI, Command
Types Device-specific, no query.
