High-Speed Multiple-Channel Analog to Digital Data-Acquisition Module for Microprocessor Systems

Intelligent data acquisition and instrumentation systems established by the incorporation of microprocessor technology require high-speed analog to digital conversion of multiple-channel input signals. Sophisticated data systems or subsystems are enabled by the microprocessor software flexibility to establish adaptive input data procedures. These adaptive procedures are enhanced by versatile interface circuitry which is software controlled.

Versatile interface for PDP-8 computers

The design, construction and three typical applications of a versatile interface for PDP-8 computers, adaptable to PDP-11 systems, are described. The interface is conceived for on-line control and data acquisition in a wide variety of physical and chemical experiments. Design principles and specifications as developed from experience are discussed. A detailed description of such a system is presented, together with three typical on-line applications in the field of ESR, ENDOR and Fourier spectroscopy.
