Evaluating Balanced Devices (balance-unbalance conversion function)
Steps for Balance-Unbalance Conversion
NOTE
When using three test ports, perform a full three-port calibration on the test ports to be
used. When using four test ports, perform a full four-port calibration.
Extend the calibration plane, if necessary, by using the port extension function or network
de-embedding function. For more on the port extension and network de-embedding
functions, see “Extending the Calibration Plane Using Network De-embedding” on
page 285.

Softkey
Function
SE-Bal
Establishes port 1 on the DUT as an unbalanced port and port 2 as a balanced
port
Bal-Bal
Establishes both port 1 and port 2 on the DUT as balanced ports
SE-SE-Bal
Establishes port 1 and port 2 on the DUT as unbalanced ports and port 3 as a
balanced port
Step 6.
Select each port on the analyzer to which a port on the DUT is connected.
