SOURce<Ch>:TDIF:IMBalance:PHASe:LPORt <lport no>
Selects balanced logical port <lport no> as the sweep port of a phase imbalance swee-
pAmplitude imbalance and phase imbalance sweep in true differential mode.
Use [SENSe<Ch>:]SWEep:TYPE IPHase to activate the phase imbalance sweep
and SOURce<Ch>:TDIF:IMBalance:PHASe:STOP STARt | STOP to define its
sweep range.
Suffix:
<Ch>
.
Channel number.
Parameters:
<lport no> Logical port number of the balanced port. The balanced port
must be defined using SOURce<Ch>:LPORt<LogPt> before it
can be selected.
Range: Depending on the number of balanced ports
defined.
Example:
*RST; SOUR:LPOR1 1,3
Reset the analyzer and combine the physical ports 1 and 3 to
the logical port 1.
SWE:TYPE IPH; :SOUR:TDIF?
Select a phase imbalance sweep. This sweep type automatically
activates the true differential mode (the query returns 1).
SOUR:TDIF:IMB:PHAS:LPOR 1; STAR -20; STOP 0
Configure the phase imbalance sweep, selecting the logical port
no. 1 and a swept phase range between -20 deg and 0 deg at
the physical port no. 3 (i.e. at the physical port with the highest
port number that belongs to the selected logical port).
CALC:PAR:SDEF 'Trc1', 'SDS12'
Create a new trace named 'Trc1' to measure the mixed mode S-
parameter Sds12.
DISP:TRAC:FEED 'Trc1'

SOURce<Ch>:TDIF:IMBalance:PHASe:STARt <arg0>
SOURce<Ch>:TDIF:IMBalance:PHASe:STOP <arg0>
Defines the start/stop phase difference of a phase imbalance sweep. Applies to source
coherence mode (SOURce<Ch>:CMODe[:STATe] ON and true differential mode
(SOURce<Ch>:TDIF[:STATe] ON).
In true differential mode, the settings only apply to the sweep port selected using
SOURce<Ch>:TDIF:IMBalance:AMPLitude:LPORt.
Use [SENSe<Ch>:]SWEep:TYPE IPHase to enable the phase imbalance sweep.
