S21 or DTF, you need to recalibrate.

Port Extension
Extends the calibrated plane by setting the delay and loss of the test signal resulting
from the electrical length and compensation fixture of the connector. In this way, you
do not need to perform extra calibration any more.
Port Extension
Enables or disables the port extension function. By default, it is disabled.
Only when the port extension function is enabled, can you set the parameters for

Sets the delay time for Port 1 extension.
The relationship between port delay and port length is correlative, as shown in the
following formula:
Port Length = Port Delay * Velocity of Light * Velocity Factor
