Patent number: 10404388Abstract: A signal leakage in a cable network may be detected by using a test device to obtain a spectrum of an electromagnetic wave propagating in vicinity of the cable network, and automatically detecting QAM channels in the obtained spectrum by detecting characteristic spectral roll-offs at boundary frequencies between QAM channels of the cable network. A test device may be used to determine which QAM channels are currently active on the cable network, thereby facilitating automatic QAM signal leakage detection.Type: GrantFiled: October 31, 2018Date of Patent: September 3, 2019Assignee: VIAVI SOLUTIONS INC.Inventors: Al Ruth, Rodney Harbison Weaver, Koji Okamoto

Patent number: 10079830Abstract: A network testing device may be linked to a dedicated remote server e.g. a cloud-based server having a unique, pre-determined address. The testing device may be configured to cease operating, become locked or limited in testing functionality after a number of startup cycles, days of use, a certain date, etc. Once the testing device is locked, the testing device may be re-activated only by establishing a connection to the server. A database of network testing devices currently in use may be provided. Once a testing device is lost or stolen, the database may be remotely updated to prevent reactivation of that testing device, so as to render the lost or stolen testing device useless for an unauthorized operator of the testing device.Type: GrantFiled: April 2, 2015Date of Patent: September 18, 2018Assignee: VIAVI SOLUTIONS INC.Inventors: Al Ruth, Brian Ice, Rodney Harbison Weaver, Koji Okamoto
