摘要: Detecting ingress of a transmitted signal into cable communication system due to radio frequency from moving vehicle and interrogation transmitter location over separate wireless link provides monitoring shielding integrity or flaws there in system. The flaw may then be precisely located closed loop fashion without risking overload the interference with upstream signaling therein by detecting strength controlling while providing user-perceptible indication which is compensated for control thus indicates proximity hand-held instrument said flaw.
