A Microcomputer Based Data Acquisition System for Versatile Mobile Data Processing 780151

A Microcomputer Based Eight Channel Data Acquisition System has been developed for customer correlation and routine vehicle field testing applications. The eight channel system includes a self-contained signal conditioning system designed for a variety of transducer types and data frequency requirements. Calibration, signal gain, and channel zero offset adjustments can be performed under software control. The microcomputer system is based on a Motorola M6800 microprocessor and a non-volatile core memory module.The paper describes the design, development, field performance, and data processing characteristics of the system and presents specific automotive applications and field test results.
