Electrical Compensation
You can activate a port extension by pressing
. Then enter the delay to the reference plane.

PORT EXTENSIONS
The end of a cable becomes the test
port plane for all S-parameter
measurements.
All S-parameters.
Intelligently compensates for 1
times or 2 times the cable's
electrical delay, depending on which
S-parameter is computed.

ELECTRICAL DELAY
Compensates for the electrical
length of a cable. Set the cable's
electrical length  1 for
transmission. Set the cable's
electrical length  2 for reflection.
Only the currently selected
S-parameter.
Only compensates for electrical
length.
