Abstract
Methods are disclosed for identifying and locating points of impairment in a cable plant, such as that used for cable television (CATV). The methods utilize both known characteristics of signals as well as propagation times in free space and within the cable in conjunction with accurate determination of locations at which measurements are taken. The methods can be applied to both RF cable leaks as well as points of ingress of interference.
