Abstract
A system for pinpointing CDP sources in a two-way HFC CATV network comprises a headend CPD radar unit, a return path switch, and a computer. The radar unit is coupled to a headend combiner. The return path switch is coupled between the nodes of the CATV network and the radar unit. The computer is connected to the radar unit and the return path switch. The computer controls the radar unit and switch and causes them to perform constant sequential CPD monitoring of the nodes of the network. The system further comprises a portable radar-calibrator unit that is carried into the field and connected to various points along the coaxial cable portion of the network. The portable radar unit is used to detect CPD sources in the field and to calibrate the network as to time delay. The portable unit communicates with the headend radar unit through the CATV network.
