A home network bandwidth diagnostic device includes a housing and a coaxial connector portion secured to the housing. The connector is adapted to electronically couple the diagnostic device to an active distribution port within a subscriber drop system. The diagnostic device further includes a radio frequency injection circuit coupled to the coaxial connector. The radio frequency injection circuit includes a signal injector configured to inject a radio frequency test signal at a first power level substantially to the subscriber drop system. The test signal is defined by a lower home network frequency and an upper home network frequency. The diagnostic device further includes a receiver test circuit having a diplexer circuit coupled to the coaxial connector. An input of the diplexer circuit is configured to accept the radio frequency test signal at a second, lower power level, and an output of the diplexer circuit includes a first test path to pass substantially only the lower home network frequency. The output of the diplexer circuit further includes a second test path to pass substantially only the upper home network frequency. The diagnostic device further includes a first indicator disposed on the first test path and a second indicator disposed on the second test path. The indicators are configured to change state when the second power level is greater than a threshold value. The diagnostic device may be used to determine if sufficient power exists in a subscriber drop system to operate home network-enabled devices, such as MoCA-enabled devices. |
