Abstract
Instrumentation and programming techniques used to convert a microwave-optical spectrometer to fully-automatic control by an S-100 bus 'personal' microcomputer are described. Most of the material presented is applicable to other types of research apparatus as well. Interfacing of frequency synthesisers, analogue-to-digital and digital-to-analogue converters, stepping motors and diverse laboratory instruments is discussed. The net result has been a significant increase in data quality and acquisition rate accompanied by a significantly reduced expenditure of human effort.
