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.
Similar to CALCulate<Ch>:PARameter:CATalog?, but in presence of balanced
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 CALCulate<Ch>:DATA:SGRoup?
.
Traces must be selected to become active traces; see CALCulate<Ch>:PARameter:
SELect.
Note: Each channel can contain a single S-parameter group only. Defining a new S-
parameter group deletes the previous one. Use CALCulate<Ch>:PARameter:
DELete:SGRoup on page 902 to delete the current S-group explicitly.
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.
Parameters:
<LogicalPort1> Logical (balanced or unbalanced) port numbers. The port num-
bers must be in ascending order, their number is limited by the
test ports of the analyzer. With n logical port numbers, the com-
mand generates n
2
traces. The traces correspond to the follow-
ing S-parameters:
S
<log_port1><log_port1>
, S
<log_port1><log_port2>
... S
<log_port1><log_port<n>>
...
S
<log_port<n>><log_port1>
, S
<log_port<n>><log_port2>
... S
<log_port<n>><log_port<n>>
,
