A Multichannel Digital Data Acquisition System

摘要

A digital data acquisition system (DIDAS) is discussed with emphasis on its concepts and capabilities. Any arbitrary combination of 43 inputs made up of 36 analog inputs, 6 digital inputs, and 1 events pulse input may be sampled at rates up to 6000 samples per second, digitized where necessary, and recorded on magnetic tape. These output digital tapes are suitable for direct entry into an IBM 7090 or similar digital computer. Since the primary function of DIDAS is to sample, digitize, and record analog data, the system is considered a 36-channel system, and it is with this principal consideration that the operational and performance characteristics are described herein.
