Note: To create a new trace and at the same time assign the attributes, use
CALCulate<Ch>:PARameter:SDEFine
. To display the trace, create a window
(
DISPlay:WINDow<Wnd>[:STATe] ON
) and assign the trace to this window
(
DISPlay:WINDow<Wnd>:TRACe:FEED
); see example below.
Traces must be selected to become active traces; see
CALCulate:PARameter:SELect
.
CALCulate<Ch>:PARameter:CATalog?
returns a list of all defined traces.
<Ch> Channel number of an existing channel containing the referenced trace.
'<string>' Trace name, e.g. 'Trc4'. See Rules for trace names in the Trace Manager
description.
'S11', ... Measurement parameter (string variable); see list of in the
CALCulate<Ch>:PARameter:SDEFine
command description.
A query of a wave quantity 'xy' returns 'xyD<n><Detector>', where <n>
numbers the source (drive) port, and <Detector> denotes the detector
setting (SAM for a normal (sample), RMS or PEAK for an RMS or peak
detector). A query of a ratio 'x/y' returns 'xD<n>/yD<m><Detector>', where
<n> and <m> number the source ports.
*RST value –

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 S11.
CALC4:PAR:MEAS 'Ch4Tr1', 'a1'
Change the measurement parameter of the trace and measure the wave
quantity a1.
CALC4:PAR:MEAS? 'Ch4Tr1'
Query the measured quantity. The response is 'A1D1SAM'.
CALCulate<Ch>:PARameter:SDEFine '<string>', 'S11' | ... | 'S0101' | ... | 'SCD11' |
... | 'Y11' | ... | 'Z11' | ... | 'SY11' | ... | 'SZ11' | ... | 'a1' | ... | 'A01' | ... | 'B1' | ... | 'B01' |
... | 'B2/A1' | ... 'B02/A01' | ... | 'Pmtr2D1' | ...
Creates a trace and assigns a channel number, a name and a measurement parameter to it. The trace
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.
Traces must be selected to become active traces; see
CALCulate:PARameter:SELect
.
<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.
