Steps For Balance-Unbalance Conversion - Agilent Technologies ENA Series User Manual

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 153.
