Filter

1.The Filter is used to reduce 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.
