Abstract: A multi-function, intelligent, distributed analysis test tool (MFDAT) suitable for performing maintenance on complex, 5 sophisticated electronic systems. MFDAT replaces ordinary test instruments such as spectrum analyzers, oscilloscopes, power meters, frequency counters and digital multimeters with modular virtual test instruments that perform the identical functions but use a single display and human interface. Setup 10 information stored internally allows automatic selection and set up the instruments for a particular test. MFDAT provides a “virtual” system to the technician whereby when a second system under test is unavailable, a previous good reading stored by MFDAT is available for comparison. MFOAT provides 15 three operating modes that allow the operator to develop, modify, or refine test procedures, use the embedded test instruments as they would use standard instruments, or to step through predefined test procedures.
