Converting reference impedance of balanced port

Converting reference impedance of balanced port
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 (see Figure 7-15).
Figure 7-15 Port Impedance After a Balance-Unbalance Conversion
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" on page 154.
