Abstract

This acquisition system is designed and built as a plug-in circuit board for IBM AT, PS/2, and compatibles. It is configured either as a 16 single-ended or 8 differential input channel system, with up to 20-bit conversion resolution potential. It can process the data at a rate up to 100 kHz. The software package includes commands needed for the system initiation, automatic or 9 software programmable gain selection, sampling and conversion, and data normalization
