Command
Types
Device-specific, command or query
Example:
See SOURce<Ch>:TDIF:IMBalance:AMPLitude:LPORt
SOURce<Ch>:TDIF:IMBalance:PHASe:LPORt <Log Port>
Selects a logical (balanced) port for the phase imbalance sweep in true differential mode. A balanced port
configuration must be defined and a phase imbalance sweep must be active to use this command; see
program example.
<Ch>
Channel number.
<Log Port>
Logical port number of the balanced port. The balanced port must be defined using
SOURce<Ch>:LPORt<log_port> before it can be selected.
Range [def.
unit]
Depending on the number of balanced ports defined. [–]

Command
Types
Device-specific, command or query
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 S
ds12
.
DISP:TRAC:FEED 'Trc1'
Display the result
SOURce<Ch>:TDIF:IMBalance:PHASe:STARt <Start Phase>
Defines the start phase for a phase imbalance sweep, which is equal to the left edge of a Cartesian
diagram. A balanced port configuration must be defined and a phase imbalance sweep must be active to
use this command; see program example.
<Ch>
Channel number.
<Start
Phase>
Start phase of the sweep.
Range [def.
unit]
–180 deg to +179.99 deg [deg]. UP and DOWN increment/decrement the phase in 1-
deg / 0.1-deg / 0.01-deg steps. The start phase must be smaller than the stop phase
