3. Always set the reference impedances of the two test ports before
balanced conversion to the same value.
4. Turn on the port reference impedance conversion function.

The reference impedance of the command mode of port 2 on the DUT is
set to 50 W . The impedance of the differential mode of that port may be
set and modified independently of setting the two-port reference
impedances before balanced conversion. For more information, see
Converting Reference Impedance of Balanced Port.
8. Adding a Matching Circuit
Here, add an inductance of 47 nH in parallel to port 2 on the DUT
(balanced). It is also possible to add a matching circuit to the port before
unbalanced-balanced conversion. For more information, see Determining
the Characteristics that Result from Adding a Matching Circuit to a
Differential Port.
• The balance matching circuit (Differential matching circuit
embedding) is not applied to single-ended S-parameter results.
For example, the balance matching circuit is not applied to the
imbalance parameter as it is derived from single-ended S-
parameters.
