SOURce<Ch>:TDIF[:STATe] <TruDi state>
Switches the True differential mode on or off. This command is available only if a suita-
ble balanced port configuration is active.
Suffix: 
<Ch>
.
Channel number.
Parameters:
<TruDi state> True differential mode ON or OFF
*RST:  OFF
Example: 
*RST; SOUR:LPOR1 1,3
Reset the analyzer and combine the physical ports 1 and 3 to
the logical port 1. Defining a balanced port configuration deletes
the default trace.
SOUR:TDIF ON
Switch true differential mode on.
CALC:PAR:SDEF 'Trc1', 'BD1D2S'
Create a new trace to measure the differential received wave
quantity bd1, using the single-ended analyzer port no. 2 as a
source port.
Options:  R&S ZNA-K61
Manual operation:  See "True Differential Mode" on page 312
SOURce<Ch>:TDIF:IMBalance:AMPLitude:LPORt <lport no>
Selects balanced logical port <lport no> as the sweep port of an amplitude imbalance
sweepAmplitude imbalance and phase imbalance sweep in true differential mode.
Use [SENSe<Ch>:]SWEep:TYPE IAMPlitude to activate the amplitude imbalance
sweep and SOURce<Ch>:TDIF:IMBalance:AMPLitude: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.
