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 S
ds12
.
DISP:TRAC:FEED 'Trc1'
Display the result.
SOURce<Ch>:TDIF:IMBalance:AMPLitude:STARt <Start Power>
Defines the start power for an amplitude imbalance sweep, which is equal to the left edge of a Cartesian
diagram. A balanced port configuration must be defined and an amplitude imbalance sweep must be
active to use this command; see program example.
<Ch>
Channel number.
<Start
Power>
Start power of the sweep.
Range [def.
unit]
–40 dBm to +9.99 dBm. The exact range depends on the analyzer model; refer to the
data sheet [dBm]. UP and DOWN increment/decrement the source power in 0.01-dB
steps. The start power must be smaller than the stop power
(SOURce<Ch>:TDIF:IMBalance:AMPLitude:STOP).
*RST value
–10 dBm

SOURce<Ch>:TDIF:IMBalance:AMPLitude:STOP <Stop Power>
Defines the stop power for an amplitude imbalance sweep, which is equal to the right edge of a Cartesian
diagram. A balanced port configuration must be defined and an amplitude imbalance sweep must be
active to use this command; see program example.
<Ch>
Channel number.
<Stop
Power>
Stop power of the sweep.
Range [def.
unit]
–39.99 dBm to +10 dBm. The exact range depends on the analyzer model; refer to the
data sheet [dBm]. UP and DOWN increment/decrement the source power in 0.01-dB
steps. The stop power must be larger than the start power
(SOURce<Ch>:TDIF:IMBalance:AMPLitude:STARt).
*RST value
+10 dBm
