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.
Cal
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.
