Circuit Diagram of Coaxial Cable Tester
Coaxial cables are used as transmission lines for radio frequency signals. But sometimes it is difficult to detect the transmission signal from input to output. Now, this is a simple cable tester, using four 2-input NOR gate IC 4001. As shown in the circuit diagram, test the coaxial cable by connecting to points A and B. The illuminated LED1 indicates that the cable string is connected internally; the illuminated LED2 indicates that the cable is disconnected, and the illuminated LED3 indicates that the cable is good.
