This article describes a circuit arrangement that isolates line faults from circuit faults and permits self-test even in the presence of an incoming signal. The increased sophistication of electronic equipment makes automated fault-isolation extremely important for many systems. One such application is found in the automotive industry where technicians are not highly skilled in electronic circuit maintenance. Computerized testing in this case must isolate faults to a single unit or component. The interface between assemblies is of special concern. Each electronics assembly should be self-testing and be able to differentiate between faults caused by its own driver/receiver, the interconnecting cable and/or the interfacing unit. Fig.
