Patent number: 10764532Abstract: Unlike conventional methods and systems for locating ingress, which only monitor the upstream path, a method and system of locating ingress by monitoring the downstream path is provided. A test system measures the signal quality in the upstream path and in dependence upon a noise level being above a predetermined limit, polls a plurality of terminal equipment devices to return a downstream signal quality measurement. The test instrument analyzes the downstream signal quality measurements to locate an ingress source contributing to the noise.Type: GrantFiled: October 30, 2013Date of Patent: September 1, 2020Assignee: VIAVI SOLUTIONS INC.Inventors: Kevin J. Oliver, Koji Okamoto, Gregory W. Massey, Walter Miller

Patent number: 10601465Abstract: Non-disruptive sweep measurements using low power coherent signals overcome the limitations of prior art frequency response systems for cable networks. Modulated or unmodulated, e.g. continuous wave (CW), test signals are transmitted into the network at a first or input point (input point is in the head end for forward sweep; input point is in the field for reverse sweep). The test signals are transmitted continuously at multiple frequencies, so as a composite they form a wideband, OFDM-like (orthogonal frequency-division multiplexing) waveform. A receiver at a second or output point generates power reading measurements, from which the frequency response of the network is produced.Type: GrantFiled: March 19, 2019Date of Patent: March 24, 2020Assignee: VIAVI SOLUTIONS INC.Inventors: Ben Maxson, Koji Okamoto
