In recognition of the ever increasing problems that manual test approaches bring, an intelligent automatic test and diagnostic system (IATDS) is being developed which is described in the paper. The system performs a functional test to electronic equipment systems under test and provides the operator with a fault diagnostic approach which combines expert system (ES) techniques and guided-probe fault detection and isolation techniques. The major objectives of the system is to decrease test time, to improve diagnostic capabilities and supply guidance to maintenance personnel.
