Terms and Descriptions The table below defines the terms used throughout the manual and provides information to assist you with proper operation and understanding of the unit and its functions. Term Description Spread Spectrum Time SSTDR is a patented technology that allows Domain Reflectometry for diagnotic testing on cables without (SSTDR) interference from voltage. Open Fault Typically an unterminated wire, broken wire, or bad connection. Short Fault Two wires making contact or connected together (closed circuit). Fault Location Testing Testing for faults that are persistent, (either a hard short or open which do not change with time). Live IFD Testing Intermittent Fault Detection (IFD) continuously tests for a fault on live or unenergized cables that can occur randomly and not persistent. Live Sweep Testing An intermittent fault detection function that is used to locate intermittent fault conditions on extremely long energized cables (≤ 6 kilometers), but also retains the ability to detect short and medium distance faults. VOP Velocity of Propagation (VOP) is the speed at which a signal travels through a cable, measured relative to the speed of light. For most cables, this is about 66% the speed of light. 4
