[SENSe<Ch>:]LPORt<log_port>:ZCOMmon <real>[, <imaginary>]
Specifies the complex common mode reference impedance for the balanced (logical) port numbered
<log_port>.
<Ch> Channel number. If unspecified the numeric suffix is set to 1.
<log_port>
Logical port number. The logical ports must be defined using
SOURce<Ch>:LPORt<log_port>
<phys_port1>,<phys_port2>
. An n port analyzer supports a
maximum of n/2 (n even) or (n – 1)/2 (n odd) logical ports.
<real>
<imaginary> Real and imaginary part of the port impedance. <imaginary> may be
omitted to define a real impedance.

Example:
*RST; CALC:PAR:DEL 'TRC1'
Reset the analyzer and delete the (default) trace
for channel no. 1.
SOUR:LPOR1 1,2
Combine the physical ports no. 1 and 2 to define the balanced (logical)
port no. 1.
LPOR1:ZCOM 27, 2
Specify a complex common mode reference impedance of 27
