The Control Event Scanner (CES) is a microprocessor-based device which will control and sense relay contract closures via the IEEE Standard 488-1975 Interface Bus, hereafter known as the General Purpose Interface Bus (GPIB). Through the use of a microcomputer, other functions such as pulse counting, analog to digital conversion, digital timing, etc., are easily implemented. With a fully implemented unit, the capability exists to realize a low-cost, fully programmable automated test fixture suitable for use in a distributed performance assessment network (DPAN). With the use of the GPIB and an internal microcomputer, on-line reconfiguration is possible to implement a variety of dedicated performance assessment instruments. Performance assessment and a fault isolation example are discussed. (Author)
