Suffix:
<Ch>
.
Channel number. <Ch> may be used to reference a previously
defined channel. If <Ch> does not exist, it is generated with
default channel settings.
Example: See CALCulate<Ch>:PARameter:DEFine:SGRoup
Usage: Event
CALCulate<Ch>:PARameter:MEASure <TraceName>, <Result>
Assigns a measurement result to an existing trace. The query returns the result
assigned to the specified trace (no second parameter; see example).
Note: To create a new trace and at the same time assign the attributes, use
CALCulate<Ch>:PARameter:SDEFine. To display the trace, create a diagram
(DISPlay[:WINDow<Wnd>][:STATe] ON) and assign the trace to this diagram
(DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:FEED); see example below.
Traces must be selected to become active traces; see CALCulate<Ch>:PARameter:
SELect. CALCulate<Ch>:PARameter:CATalog? returns a list of all defined traces.
You can open the "Trace Manager" dialog to obtain an overview of all channels and
traces, including the traces that are not displayed.
Suffix:
<Ch>
.
Channel number of an existing channel containing the refer-
enced trace.
Parameters:
<TraceName> Trace name, string variable, e.g. 'Trc4'. See "Rules for trace
names" in "Table Area" on page 305. Trace names must be
unique across all channels and diagrams.
<Result> Measurement parameter (string variable); see Table 8-4.
A query of a wave quantity 'xy'
returns'xyD<n><Detector>', where <n> numbers the source
(drive) port, and <Detector> denotes the detector setting. A
query of a ratio 'x/y' returns 'xD<n>/yD<m><Detector>',
where <n> and <m> number the source ports
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the
input reflection coefficient S
11
.
CALC4:PAR:MEAS 'Ch4Tr1', 'a1'
Change the measurement parameter of the trace and measure
the wave quantity a
1
.
CALC4:PAR:MEAS? 'Ch4Tr1'
Query the measured quantity. The response is 'A1D1SAM'.
Manual operation: See "S-Parameter (selector)" on page 256
