Abstract : The patent describes an apparatus for testing an incremental shaft encoder in which the encoder is placed upon a rate table together with a gyroscope to permit coincident rotation. Every time the shaft of the incremental shaft encoder turns through a complete cycle, the leading edges of a square wave output generated by the encoder, start and stop a counter which is fed by a frequency signal derived from the rotating gyroscope through a voltage-to-frequency converter. The counter output then is applied to a printer.
