About the DSP TDR
In the event of a cable break or fault, the DSP TDR enables cable service provider maintenance
teams and contractors to quickly find the location to get service back online as soon as
possible. Since a cable break likely means an outage, pin-pointing it quickly is very important.
Length measurement accuracy is also critically important, as often the cable is underground
and must be dug out to make the splice. A lack of precision in this measurement means a
bigger hole must be dug. A TDR is needed to find breaks and faults, to keep the operator from
paying for unnecessary span replacements.
The DSP TDR is designed for field use and has step technology, which enables it to show
smaller faults, has no blind spot, and maintains accuracy for detecting impedance over the
entire length of the cable. Automatic impedance matching allows for faster trace results
without pulse width adjustments. In addition to the ability to find faults closer to the TDR (no
blind spot) the TDR has a resolution of less than 1 foot (0.3m). The higher energy step TDR has
an improved signal-to-noise ratio and digital averaging, eliminating noise interference, and
producing a much more detailed cable image than available with a pulse TDR.
