CALCulate<Ch>:PARameter:MEASure
<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).
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 diagram
ON
) and assign the trace to this diagram
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:FEED
); see example below.
Traces must be selected to become active traces; see
CALCulate<Ch>:PARameter:CATalog?
returns a list of all defined traces.
You can open the "Trace Manager" dialog to obtain an overview of all channels and
traces, including the traces that are not displayed.
Suffix:
<Ch>
.
Channel number of an existing channel containing the refer-
enced trace.
Parameters:
<TraceName>
Trace name, string variable, e.g. 'Trc4'. See "Rules for trace
names" in
on page 337. Trace names must be
unique across all channels and diagrams.
<Result>
Measurement parameter (string variable); see
.
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
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>
)
