Example:
*RST; SOUR:LPOR1 1,3
Reset the analyzer and combine the physical ports 1 and 3 to
the logical port 1.
SWE:TYPE IAMP; :SOUR:TDIF?
Select an amplitude imbalance sweep. This sweep type auto-
matically activates the true differential mode (the query returns
1).
CALC:TDIF:IMB:COMP ON
Use imbalance-compensated wave quantities to calculate S-
parameters, ratios and derived quantities.
SOUR:TDIF:IMB:AMPL:LPOR 1; STAR -20; STOP 0
Configure the amplitude imbalance sweep, selecting the logical
port no. 1 and a swept power range between -20 dBm and 0
dBm 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'

R&S ZNA-K61
Manual operation: See "Amplitude > Port / Start Power / Stop Power" on page 706
SOURce<Ch>:TDIF:IMBalance:AMPLitude:STARt <arg0>
SOURce<Ch>:TDIF:IMBalance:AMPLitude:STOP <value>
Defines the start/stop power difference of an amplitude 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 port selected using
SOURce<Ch>:TDIF:IMBalance:AMPLitude:LPORt.
Use [SENSe<Ch>:]SWEep:TYPE IAMPlitude to activate amplitude imbalance
sweep.
Suffix:
<Ch>

Channel number.
Parameters:
<value> Start/stop power difference of an amplitude imbalance sweep
