'S11', ...
Measurement parameter (string variable); see list of in the
CALCulate<Ch>:PARameter:SDEFine command description.
*RST value –
SCPI,
Command
Types
Device-specific, with query (see 'S11',... parameter description above).
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the input reflection
coefficient S
11
.
CALC4:PAR:MEAS 'Ch4Tr1', 'S12'
Change the measurement parameter of the trace and measure the transmission
coefficient S
12
.
CALC4:PAR:MEAS? 'Ch4Tr1'
Query the measured quantity. The response is 'S12'.
CALCulate<Ch>:PARameter:SDEFine '<string>', 'S11' | ... | 'Y-S11' | ... | 'Z-S11' | ...
Creates a trace and assigns a channel number, a name and a measurement parameter to it. The trace
becomes the active trace in the channel but is not displayed.
To display the trace defined via CALCulate<Ch>:PARameter:SDEFine, create a window
(DISPlay:WINDow<Wnd>[:STATe] ON) and assign the trace to this window
(DISPlay:WINDow<Wnd>:TRACe:FEED); see example below.
CALCulate<Ch>:PARameter:MEASure changes the measurement parameter of an existing
trace.
To select an existing trace as the active trace, use CALCulate:PARameter:SELect. You can open the
trace manager (DISPlay:MENU:KEY:EXECute 'Trace Manager') to obtain an overview of all
channels and traces, including the traces that are not displayed.
In FW versions <V1.90, traces created with CALCulate<Ch>:PARameter:SDEFine must be
selected explicitly (CALCulate:PARameter:SELect) in order to become active traces.
<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', ...
Measurement parameter (string variable); see list of parameters below.
*RST value –
SCPI,
Command
Types
Device-specific, no query. CALCulate<Ch>:PARameter:MEASure?
'<Trc_name>' queries the measurement parameter of the trace.
CALCulate<Ch>:PARameter:CATalog? returns a list of all defined traces.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the input reflection
coefficient S11.
