Suffix:
<Ch>
.
Channel number
Setting parameters:
<TraceName> Trace name
<Result> Measured quantity
Manual operation: See "S-Parameter (selector)" on page 285
CALCulate<Ch>:PARameter:SDEFine <TraceName>, <Result>
Creates a trace and assigns a channel number, a name and a measurement parame-
ter to it. The trace becomes the active trace in the channel but is not displayed.
Note: To display the trace defined via CALCulate<Ch>:PARameter:SDEFine, cre-
ate a diagram (DISPlay[:WINDow<Wnd>][:STATe] ON) and assign the trace to this
diagram (DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:FEED); see example below.
CALCulate<Ch>:PARameter:MEASure changes the measurement result of an
existing trace.
To select an existing trace as the active trace, use CALCulate<Ch>:PARameter:
SELect. You can open the trace manager to obtain an overview of all channels and
traces, including the traces that are not displayed.
Tip: This command has no query form. Use CALCulate<Ch>:PARameter:MEASure
<TraceName> to query the measurement result of the trace. CALCulate<Ch>:
PARameter:CATalog? returns a list of all defined traces.
Suffix:
<Ch>
.
Channel number referencing a previously defined channel. If
<Ch> does not exist, it is generated with default channel set-
tings.
Setting parameters:
<TraceName> Trace name, string variable, e.g. 'Trc4'. See "Rules for trace
names" in "Table Area" on page 337. Trace names must be
unique across all channels and diagrams.
If a trace with the selected trace name already exists, the ana-
lyzer behaves as follows: If the existing trace is assigned to the
same channel as the new trace, it is deleted. The new trace is
not automatically assigned to a diagram area; see note above.
If the existing trace is assigned to a different channel, no new
trace can be created. The analyzer returns an error message.
<Result> Measurement result (string variable), see table below.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the
input reflection coefficient S
11
.
DISP:WIND2:STAT ON
Create diagram area no. 2.
DISP:WIND2:TRAC:FEED 'CH4TR1'
Display the generated trace in diagram area no. 2.
