Extending The Calibration Plane Using Network De-Embedding; Using The Network De-Embedding Function - Agilent Technologies ENA Series User Manual

Extending the Calibration Plane Using Network
De-embedding
Network de-embedding is a function for performing measurements, test port by test port,
by removing the characteristics of an arbitrary network defined by a Touchstone data file.
By removing the characteristics of the cable, test fixtures, etc. between the actual
calibration plane and the DUT, the calibration plane can be correspondingly extended. The
network de-embedding function can be used together with the port extension function (see
Figure 7-2).
