ABSTRACT:
A coaxial cable testing and tracing device including a plurality of cable terminator plugs each having a characteristic impedance; an electrical testing circuit further including a coaxial cable connector coupleable to an end of a coaxial cable, a signal generating mechanism coupled to the cable connector for generating and transmitting a plurality of characteristic signals with one of the signals indicating an open circuit condition at the cable connector and with the other remaining signals indicating that a coaxial cable coupled to the cable connector has been terminated with a cable terminator plug, and a display mechanism coupled to the signal generator mechanism for receiving a signal therefrom and based on this received signal providing a visual indication of when a coaxial cable coupled to the cable connector has been terminated with a terminator plug and further providing an indication of an open circuit condition at the cable connector; a power supply mechanism for supplying electrical energy; and a power switch mechanism coupled between the power supply mechanism and testing circuit.
