This dual role of predicting future failure conditions and isolating existing problems makes DTF an important part of service and maintenance on transmission lines.

DTF displays RF return loss or VSWR data versus distance.

Replacing all the cables frequently is an expensive proposition.These common problems can cause unwanted signal reflections.Poorly tightened connectors and poor environmental seals are exacerbated by acid rain corrosion.The FDR measurement technique requires a swept frequency input to the transmission line.An inverse FFT (Fast Fourier Transform) is performed on the reflected signals transforming this information into the time domain.

The attenuation per foot or meter for the cable is also required in order to compensate for the attenuation versus distance.
