VXI synchro/resolver measurement and simulation COTS hardware for Turkish Airforce F-16 depot program ATE

This paper describes the WesTest Engineering Corp. automatic test equipment (ATE) system, and the NAI, Inc VXI commercial-off-the-shelf (COTS) synchro/resolver resource card, used in the Turkish Airforce F-16 Depot Maintenance Program. The WesTest ATE system incorporates an open architecture VXIbus-based design and provides a general-purpose test capability for analog, digital, and hybrid assemblies, sub-assemblies and circuit cards. The ATE system is expandable and reconfigurable, end it is built to commercial specifications. All of the instruments in the tester are commercial-off-the-shelf (COTS) units, including the NAI Model 5390 synchro/resolver resource. NAI's model 5390 is a C size precision Synchro/Resolver Simulation and Angle Position Measurement VXI COTS tester card. It can simulate and measure synchro and resolver angles with a resolution of 0.001 degrees and an accuracy of +/- 0.004 degrees. Interfacing to rugged reliable synchros, the 5390 functionality is based upon highly accurate synchro-to-digital conversion and digital-to-synchro simulation.
