[SENSe<Chn>:]SWEep:SRCPort
<Port>
Sets/gets the source port for the stimulus signal. The setting acts on the active trace.
The effect of the drive port selection depends on the measurement parameter associ-
ated to the active trace:
●
If an S-parameter S
<out><in>
is measured, the second port number index
<in>
(input
port of the DUT = drive port of the analyzer) is set equal to the selected drive port:
Drive port selection affects the measured quantity.
●
If a wave quantity or a ratio is measured, the drive port is independent of the mea-
sured quantity:
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Port>
Logical port number
*RST:
1
Example:
CALC4:PAR:SDEF "Ch4Tr1", "A1"
Create channel 4 and a trace named "Ch4Tr1" to measure the
wave quantity a
1
. The trace automatically becomes the active
trace.
SENS4:SWE:SRCP 2
Select drive port 2 for the active trace.
CALC4:PAR:MEAS? "Ch4Tr1"
Query the measurement result for "Ch4Tr1". The response is
'A1D2SAM'

[SENSe:]UDSParams:ACTive
<arg0>
With a "set to OFF", this command disables user-defined physical ports (see
ter 5.3.1.2, "Redefined S-Parameters"
on page 117). In "get direction" it queries
whether or not user-defined phasical ports are configured.
Note
that a "set to ON" doesn't have any effect; user defined ports can ony be created
Parameters:
<arg0>
OFF (0) or ON (1)
Example:
Manual operation:
See
[SENSe:]UDSParams<Pt>:PARam
<PortString>
Creates or redefines a user-defined physical port (see
Chapter 5.3.1.2, "Redefined S-
on page 117). This causes a factory reset.
