Overview
By using the port impedance conversion function, you can specify the
impedance of each test port. As a result of this conversion, the impedance
of the balanced port in differential mode is set to a value twice as large as
the impedance of the two unbalanced ports before conversion, and in
common mode to a value one-half as large.
Be sure to set the impedances of the two unbalanced
ports equal to each other. For more details on setting up port
impedance for unbalanced ports, refer to Converting the Port
Impedance of the Measurement Result.
Port impedance after a balance-unbalance conversion
As described above, the impedance of the balanced port is automatically
specified as the result of specifying the impedance of the two unbalanced
ports prior to balance-unbalance conversion. However, the port impedance
