An inexpensive but versatile data acquisition system has been developed with the use of a modified IBM-DACA (IBM Personal Computer Data Acquisition and Control Adaptor). With the modification described, the IBM-DACA can be operated in more various modes of operation. Data can be read either by software trigger or by hardware trigger mode. Also, all the three channels of the on-board timer/counter can be fully utilized for complex or accurate timing and experiment control. This allows gated data acquisition with user-specified timing and a maximum A/D throughput to memory of up to 18520 samples/s in a single channel. With its menu-driven software, this system can be used in various scientific data acquisition environments with minimal expense.

PC-based data acquisition systems are used in a wide variety of applications. In laboratories, in field services and in manufacturing facilities, these systems act as general-purpose measurement and control tools well suited for measuring voltage signals. Teaching and learning experiences may be enhanced by integrating new-technologies in the engineering curriculum, particularly in experimental-type courses. By installing plug-in data acquisition boards and signal-conditioning hardware, and appropriate software, the general-purpose computers become enormously flexible virtual-instruments with data acquisition and analysis capability. This paper describes a Computer-Aided Testing System which uses a commercially available A/D board to offer users a wide array of measurement and control capabilities. It can be used for making repeated high speed measurement, controlling motors or teaching data acquisition.
