Abstract
We describe a small size low cost 128-256 channels multichannel analyser based on an SDK85 microcomputer board using a minimum of external low cost circuitry. This circuitry consists only of a quad comparator, three operational amplifiers and three integrated analog switches and very few discrete components. The pulse amplitude conversion is carried out fully by software. This software as well as that for data acquisition and output functions is described and results are presented.
