CALCulate<Ch>:PARameter:CATalog?
Returns the trace names and measurement parameters of all traces assigned to a particular channel.
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
Response
String parameter with comma-separated list of trace names and measurement
parameters, e.g. 'CH4TR1,S11,CH4TR2,S12'. The measurement parameters are
returned according to the naming convention of
CALCulate<Ch>:PARameter:SDEFine. The order of traces in the list reflects their
creation time: The oldest trace is the first, the newest trace is the last trace in the list.

Types
Device-specific, query only.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the input reflection
coefficient S11.
CALC4:PAR:CAT?
Query the traces assigned to channel 4. If Ch4Tr1 is the only trace assigned to
channel 4, the response is 'CH4TR1,S11'.
CALCulate<Ch>:PARameter:DEFine '<string>', S11 | S12 | S21 | S22
Creates a trace and assigns a channel number, a name and a measurement parameter to it. The trace is
not displayed. To display a trace defined via CALCulate<Ch>:PARameter:DEFine, a window must be
created (DISPlay:WINDow<Wnd>[:STATe] ON) and the trace must be assigned to this window
(DISPlay:WINDow<Wnd>:TRACe:FEED); see example below.
Traces must be selected to become active traces; see CALCulate:PARameter:SELect.
This command has been implemented for compatibility reasons. The parameter names in this
command differ from ZVL conventions; moreover the parameter list is not complete. The
alternative command CALCulate<Ch>:PARameter:SDEFine uses a complete parameter list with
compatible names.
<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.
'<string>' Trace name, e.g. 'Trc4'. See Rules for trace names in the Trace Manager
description.

Types
Device-specific, no query. CALCulate<Ch>:PARameter:CATalog? returns a list
of all defined traces.
Example:
CALC4:PAR:DEF 'Ch4Tr1', S11
