Port Extensions and Loss Values

Setting port extensions
Port Extension is a function for moving the calibration reference plane by
specifying the electrical delay. This function is useful, for example, when
you cannot directly perform calibration at the DUT terminal because the
DUT is inside the test fixture. In such a case, this function enables you to
first perform calibration at the test fixture terminal and then move the
calibration plane to the DUT terminal by extending the port.
Port extension corrects the electrical delay of each test port (phase shift)
only. It cannot remove errors caused by the loss in and incorrect matching
of cables, adapters, or test fixtures.
You can define port extension channel by channel. Setting port
