<Result> Measurement parameter (string variable); see Table 7-4.
A query of a wave quantity 'xy' returns
'xyD<n><Detector>', where <n> numbers the source (drive)
port, and <Detector> denotes the detector setting. A query of
a ratio 'x/y' returns 'xD<n>/yD<m><Detector>', where
<n> and <m> number the source ports
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', 'a1'
Change the measurement parameter of the trace and measure
the wave quantity a
1
.
CALC4:PAR:MEAS? 'Ch4Tr1'
Query the measured quantity. The response is 'A1D1SAM'.
Manual operation: See "S-Parameter (selector)" on page 345
CALCulate<Ch>:PARameter:MEASure:SENDed <TraceName>, <Result>
Assigns a measurement result to an existing trace. The query returns the result
assigned to the specified trace (no second parameter; see example).
Similar to CALCulate<Ch>:PARameter:MEASure, 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
Setting parameters:
<TraceName> Trace name
<Result> Measured quantity
Manual operation: See "S-Parameter (selector)" on page 345
CALCulate<Ch>:PARameter:SDEFine <TraceName>, <Result>
Creates a trace and assigns a channel number, a name and a measurement parame-
ter to it. The trace becomes the active trace in the channel but is not displayed.
Note: To display the trace defined via CALCulate<Ch>:PARameter:SDEFine, cre-
ate a diagram (DISPlay[:WINDow<Wnd>][:STATe] ON) and assign the trace to this
diagram (DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:FEED); see example below.
CALCulate<Ch>:PARameter:MEASure changes the measurement result of an
existing trace.
To select an existing trace as the active trace, use CALCulate<Ch>:PARameter:
SELect. You can open the trace manager to obtain an overview of all channels and
traces, including the traces that are not displayed.
