DTF (Distance to Fault) Measurements

CAT Mode Distance to Fault (DTF) measurements are generally used to locate
problems, or faults, in a length of cable or transmission line. In this chapter, the
cable to be tested is referred to as the DUT (Device Under Test).
Settings that are NOT unique to DTF measurements are documented in the
Chapter 3, "CAT (Cable and Antenna Test) Mode."
