- Page 57 In cable testing it is common practice to specify the signal propagation velocity in term of half the actual velocity. When employing the reflection technique, this is a usual way of taking twice the signal travel path into account. To depict a reflection on the screen, the signal has to travel from the meter to the fault and back.
