Learning the NVP of a Cable
The FrameScope can determine the NVP (Nominal Velocity of
Propagation) of a cable, for use in certification testing. NVP is
expressed as a percentage of the speed of light. you must use a
sample of the cable at least 50 feet (15 meters) long. Longer
cable samples produce more accurate results.

1Measure the length of a sample of the cable.
2Connect the cable sample to the FrameScope. Do not connect the
DualRemote.
3On the Expert mode Tools menu (see page-134), press Learn NVP.
