2. The TDR Cable Fault Finder
The Triplett TDR is a hand held battery powered unit designed to measure
the length of copper power and communication cables, or indicate the
distance to a fault on the cable, given access to one end only.
Advanced signal processing techniques enable the TDR to identify opens
and short circuits, and directly indicate the fault distance on an alpha-nu-
meric display.
An internal library of standard cable types enables accurate measurement
without the necessity of entering Velocity of Propogation or Characteristic
Impedance information.
The TDR also incorporates an oscillating tone generator, that is detect-
able with a Triplett Hound, Hound 2, or Hound 3, for use in the tracing and
identification of cable pairs.
The TDR can be used to:
Measure the length of cable on a drum, without the need to unwind, and
given access to one end only.
Measure segment lengths in a Local Area Network, and distance to a fault.
Locate the distance to a fault on an installed cable run.
