Abstract:
A coaxial cable tester device includes a transmitter unit and a receiving unit. The transmitter unit includes first and second coaxial connectors, each having a center conductor and a ground conductor. There are means for isolating the ground conductors of the first and second connectors from each other. There is a power supply having first and second terminals, one connected to the center conductors and the other to the ground conductors of the first and second connectors. A short indicator circuit is connected across the terminals; the short indicator circuit includes a short switch and an indicator device in series. The receiver unit includes third and fourth coaxial connectors, each having a center conductor and a ground conductor. There are means for isolating the ground conductors of the third and fourth connectors. A first switch is connected between the ground conductors of the third and fourth connectors and a second switch is connected between the center conductors of the third and fourth connectors.
