Abstract
A test circuit and method for determining the operating status of a coaxial cable, the coaxial cable including an internal conductor and an external conductor. The test circuit comprises a measurement terminal, a resistor coupled to the internal conductor adjacent a first end of the coaxial cable and the measurement terminal, a second resistor coupled to the internal conductor adjacent a second end of the coaxial cable and to a reference voltage, and a measurement device coupled to the measurement terminal for producing an output that is reflective of the operating status of the coaxial cable. In one embodiment, the measurement device comprises a voltage comparator logic output circuit. In another embodiment, the measurement device comprises an ohmmeter.
