Abstract:
A digital synchro/resolver bridge for use in testing electrically operated synchros or resolvers of the type adapted to generate electrical signals of varying voltage, current, or phase in response to rotational movement of a first member relative to a second member, said digital bridge comprising:first and second transformer coil assemblies being sized, shaped and oriented to generate electrical signals at terminals thereof, said electrical signals having predetermined voltage, current, impedance, or phase characteristics to simulate the output of the synchro or resolver at predetermined rotational positions of the first member relative to the second member; a microprocessor; a plurality of relays electrically coupled to said microprocessor; said plurality of relays being coupled to discrete positions spaced along the windings of said transformer coil assemblies; each of said plurality of relays being coupled to one of said terminals; each of said plurality of relays being selectively actuatable by said microprocessor to alternately couple and de-couple said terminals to said discrete positions along the windings; a memory storage device electrically coupled to said microprocessor and being capable of accepting computer readable program code therein to control the operation of said microprocessor; and said memory storage device being capable of accepting computer readable data therein to match individual ones of said plurality of relays to each of said predetermined angular positions ranging from 0 to 360 degrees.
