摘要： The testing device of the present invention includes an RF input for connecting to a subscriber network, which has been disconnected from a communication network, for receiving ingress RF signals leaked into the subscriber network from outside sources. The device includes a signal processor for scanning the RF signals for power levels at a plurality of frequencies, and generating power level signals based at least in part on the power levels. Ideally, the power levels are compared to a threshold power level representing an acceptable amount of ingress, and a pass/fail indicator is displayed based on whether the power levels exceed the threshold power level.

摘要： An apparatus that includes a coupling, a signal level measurement circuit, a communication circuit and a processing circuit. The coupling is configured to connect to and received broadband RF signals from a coaxial cable termination of a communication network. The signal level measurement circuit is operably coupled to the coupling, and is operable to generate signal level measurements regarding a first set of the broadband RF signals. The communication circuit operable to obtain voice over internet protocol data packets from a second set of broadband RF signals. The processing circuit is operably connected to the communication circuit, and is operably connected to receive signal level measurements from the signal level measurement circuit. The processing circuit is operable to obtain diagnostic data relating to the second set of broadband RF signals. The processing circuit is further operable to cause communication of information representative of the signal level measurements and the diagnostic data in human-perceptible form.
