Abstract
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. A first indicator means is connected between the center and ground conductors of the third connector and second indicator means are connected between the center and ground conductors of the fourth connector.
