6. Extending the Calibration Plane (removing the cause of error)

In this section you will use the port extension function to remove an electrical delay caused
by cables or fixtures located between the calibration reference plane and the DUT to be
evaluated. If you can provide a two-port Touchstone data file representing the
characteristics of the network to be removed, the network removal function allows you to
remove the network and extend the calibration reference plane.
Follow the procedure below to set port extension for each test port.
Setting Description
Port extension of test port 1: 260 ps
Port extension of test port 2: 260 ps
Port extension of test port 3: 260 ps
Port extension: ON
Figure 14-29 shows the results of extension of the calibration reference plane.
