Clear
Clears the saved calibration coefficients.
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 its parameters.
Port 1 Delay
Sets the delay time for Port 1 extension.
The relationship between port delay and port length is correlative, as shown in the
following formula. Once one of the parameters is modified, other parameters will also
be modified.

Sets the length unit for port extension: meter or feet. The default unit is meter.
Port 1 Length
Sets the extension length for Port 1. You should set it based on the actual parameters
of the cable for the port.
