ABSTRACT:
Apparatus is disclosed which is controlled via computer interface logic for converting digital signals corresponding to predetermined synchro/resolver shaft angles into analog signals for stimulus purposes, and for converting the analog signals into digital words for measurement purposes. External synchro/resolver shaft angle signals may be converted into digital words for like purposes. The apparatus has a plurality of converter channels, each of which is controlled by the computer interface logic for operation independent of the other channels. The apparatus so configured is particularly adaptable for providing stimuli and measurements which are useful in test systems applications.
