Setting 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.
NOTE
You can define port extension channel by channel. Setting port extension for one particular
channel does not affect other channels.
