Manual operation:
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
diagram (DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:FEED); see example below.

existing trace.
To select an existing trace as the active trace, use
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
<TraceName> to query the measurement result of the trace.

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.
Measurement result (string variable), see table below.
