CALCulate<Ch>:PARameter:SDEFine:SENDed
<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.
CALCulate<Ch>:PARameter:SDEFine
, 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
Usage:
Setting only
Manual operation:
CALCulate<Ch>:PARameter:SELect
<TraceName>
Selects an existing trace as the active trace of the channel. All trace commands with-
out explicit reference to the trace name act on the active trace (e.g.
CALCulate<Ch>:PARameter:SELect
is also neces-
sary if the active trace of a channel has been deleted.
Suffix:
<Ch>
.
Channel number.
Parameters:
<TraceName>
Trace name, e.g. 'Trc4'. See "Rules for trace names" in
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named
Ch4Tr1
to measure the
input reflection coefficient S
11
. The trace is the active trace in
channel 4.
CALC4:PAR:SDEF 'Ch4Tr2', 'S22'
Create another trace named
Ch4Tr2
to measure the output
reflection coefficient S
22
. Again this new trace becomes the
active trace in channel 4.
CALC4:PAR:SEL 'Ch4Tr1'
Select the first trace
Ch4Tr1
as the active trace.
CALC4:FORM MLIN
Calculate the magnitude of S
11
and display it in a linearly scaled
Cartesian diagram.
