Abstract
An in-house custom designed data acquisition, instrument control and interactive analysis system has been integrated into the molecular spectroscopy laboratory. The system provides data acquisition and instrumental control for both high resolution spectrometers in the laboratory. Real time digital filtering as well as programmed control of the spectrometers has increased data acquisition rates. Thus the state of the art lifetime of the instruments has effectively been extended by increasing the quantity of data which may be obtained during actual instrumental state of the art lifetime. In addition, the interactive measurement and analysis capabilities are designed to reduce the difficulty and time lapse normally encountered in the labor intensive phase of measurement and analysis of very high resolution spectral data. The data acquisition and control system spools data from a maximum of four infrared detectors and controls up to 48 instruments functions. Eight additional analog sense lines (A/D) and eight analog control lines (D/A) are provided. These lines are used for prism predisperser control, plotting, etc. Real time data display is available on a closed circuit television system; interactive measurement and preliminary analysis capability is provided by a light pen interactive graphic display. Bulk storage is available on magnetic tape and disc systems and spooling of jobs for the local batch processor facility is accomplished using an industry compatible tape system.
