Microprocessor system for control and data acquisition in a millimetre-wave spectrometer

Abstract

A description is given of a millimetre-wave spectrometer controlled by a dedicated microprocessor system. This system, built around an Intel 8085A microprocessor, samples, digitises and stores the spectroscopic repetitive waveform and executes on the stored data some automatic data processing operations such as smoothing, baseline suppression and frequency calculation. New results on the millimetre-wave spectrum of CO in very high vibrational states (v3O are briefly given as an illustration of the use of this system for the study of transient species.
