CALCulate<Ch>:PARameter:CATalog?
Returns the trace names and measurement parameters of all traces assigned to a par-
ticular channel.
The result is a string containing a comma-separated list of trace names and measure-
ment parameters, e.g.
'CH4TR1,S11,CH4TR2,S12'
. The measurement parameters
are returned according to the naming convention of
. 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.
Suffix:
<Ch>
.
Channel number. If unspecified the numeric suffix is set to 1.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the
input reflection coefficient S
11
.
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'
.
Usage:
Query only
CALCulate<Ch>:PARameter:CATalog:SENDed?
Returns the trace names and measurement parameters of all traces assigned to a par-
ticular channel.

ports this command distinguishes between
●
single-ended S-parameters for
logical
ports (
SSS<Li><Lj>
)
●
"raw" single-ended S-parameters referring to
physical
ports (
S<Pi><Pj>
)
Suffix:
<Ch>
.
Channel number. If unspecified the numeric suffix is set to 1.
Usage:
Query only
CALCulate<Ch>:PARameter:DEFine:SGRoup
<LogicalPort1>, <LogicalPort2>...
Creates the traces for all S-parameters associated with a group of logical ports (S-
parameter group). The traces can be queried using
.
Traces must be selected to become active traces; see
.
Note:
Each channel can contain a single S-parameter group only. Defining a new S-
parameter group deletes the previous one. Use
on page 649 to delete the current S-group explicitly.
