Using a cable network tester configured to generate chirped probe pulses and to perform pulse-matched filtering and averaging of received echoes, network faults may be detected without interfering with the downstream reception. The probe pulse transmission may be timed to take advantage of the error correction coding in the network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance to fault measurements in cable TV networks","description":"A TDR technique for performing in-service distance-to-fault measurements in cable TV networks is disclosed.
