Functions for balanced port (option 313, 314, 413, or 414)

The following two functions are applied to a balanced (differential) port converted by
balance-unbalance conversion.
Differential port impedance conversion
A function for converting the differential mode port impedance of a balanced port after an
balance-unbalance conversion. Balance-unbalance conversion automatically converts the
differential mode port impedance at the balanced port into 2Z0 and the common mode port
impedance into Z0/2, compared with the two pre-conversion port impedances of Z0.
Differential port impedance conversion further converts a differential port impedance after
balance-unbalance conversion into an arbitrary port impedance.
For the setup procedure of differential port impedance conversion, see "Converting
reference impedance of balanced port" on page 165.
Differential matching circuit embedding
A function for converting the measurement results obtained from balance-unbalance
conversion into a characteristic under the condition of inserting a matching circuit in the
balanced port.
For setup procedure of differential matching circuit embedding, see "Determining the
Characteristics that Result from Adding a Matching Circuit to a Differential Port" on
page 167.
