Chapter 6
TDR Testing and Fault Location
Introduction
This chapter describes the CopperPro's TDR (Time Domain Reflectometer)
test. The TDR testing function is a separately packaged and purchased
software option that can often help you locate loop faults with greater
precision than the parametric fault location tests that are described Chapter 4.
With TDR, not only can you confirm the results of the basic parametric tests,
but when you use TDR in conjunction with those tests, you can also vastly
improve your ability to accurately measure the distance to faults in a cable.
The TDR Auto-Test function combines both frequency domain (parametric)
and time domain (TDR) testing functions in the same package. This
combination not only provides a rapid learning curve (due to the consistent
user interface), but also gives you with a truly powerful—yet cost-effective—
testing solution.
