NVP
Nominal velocity of propagation, which is used with the measured propagation delay to determine
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 15 m (50 ft) long.
The recommended length is 30 m (100 ft).
Increasing the NVP increases measured length.
