A program, AQ, has been developed to perform analog-to-digital (A/D) conversions on IBM PC products using the Data Translation DT2801-A or DT2801 boards. This program provides support for all of the triggered and continuous A/D modes of these boards. Additional subroutines for management of data files and display of acquired data have also been developed. These programs have been written so that a minimum number of keystrokes are required for their operation. Parameter files are used to simplify reconfiguration of this program for various data acquisition tasks.
