Page 22: Time-Domain Reflectometer Principles
Time-Domain Reflectometer Principles A Time-Domain Reflectometer (TDR) is a device using a principle similar to radar to measure time and distance over a length of cable. A TDR sends out a pulse of energy and measures the reflections to events along the length of the cable. -
Page 23: Time-Domain Reflectometer Concepts
Time-Domain Reflectometer Concepts There are several basic concepts that will help you to accurately locate and interpret the waveforms you will see on the TDR. You can use these concepts to help identify the waveforms you are analyzing. Velocity of Propagation (Vp) A cable’s velocity of propagation (VoP or Vp) specification is simply a measure of how fast a signal travels in the cable. - Page 24 Time-Domain Reflectometer Concepts (cont’d) Interpreting Waveforms Leading Edge Open Short Marker • OPEN (Capacitive Fault): Will cause the waveform display to break above the plane of the pulse reference line. • SHORT (Resistive Fault): Will cause the waveform to dip below the plane of the pulse reference line.
