Filter

external noise from the
trace.
Velocity of Propagation
1. The velocity of propagation is a measure of how fast a pulse
travels in a circuit.
2. To get the most accurate distance measurement the VP
should be set to the value for the cable type and gauge you
are testing.
3. If you do not know the VP,
we recommend you use the
TDR Setup menu. In this
menu, you will select the
type of wire you are testing
and the tester will choose
the VP.
