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 | ... | S44 | A | B | C | D | R1 | R2
| R3 | R4 | AB | AC | AD | BA | BC | BD | CA | CB | CD | DA | DB | DC | AR1 | ... | DR4 |
R1A | ... | R4D | R1R2 | ... | R4R3, [<numeric_value>]
[Deprecated command]
Creates a trace and assigns a channel number, a name and a measured quantity 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 ZVA 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.
S11, ... R4R3
Measured quantity; see list of parameters below.
*RST value
–
[<numeric_value>]
Test port number, driving port for wave quantities and ratios, ignored for S-
parameters.
Range [def. unit]
1 to 4 [–] (depending on instrument model)
*RST value

SCPI, Command
Types
Device-specific, no query. CALCulate<Ch>:PARameter:CATalog? returns
a list of all defined traces.
Example:
CALC4:PAR:DEF 'Ch4Tr1', S11
Create channel 4 and a trace named Ch4Tr1 to measure the input reflection
coefficient S11.
DISP:WIND:STAT ON
Create diagram area no. 1.
DISP:WIND:TRAC2:FEED 'CH4TR1'
Display the generated trace in diagram area no. 1, assigning a trace number
2.
The measured quantity is selected by means of the following keywords (the selection depends on the
number of test ports of the analyzer, e.g. S44 is not available on 2-port analyzers):
