SETUP > Twisted Nominal velocity of propagation, which is used with the measured propagation delay to determine
Pair > NVP cable length. The default value defined by the selected cable type represents the typical NVP for that
cable type. You may enter a different value if necessary. To determine the actual value, change the
NVP until the measured length matches the known length of a cable. Use a cable at least 30 m
(100 ft) long. See page 12-10.
Increasing the NVP increases measured length.
SETUP > Twisted The Outlet Configuration setting determines which cable pairs are tested and which pair numbers are
