A multichannel, general-purpose data logger

Abstract

This thesis describes the implementation of a general-purpose, microprocessor-based Data Logger. The Hardware allows analog data acquisition from one to thirty two channels with 12 bit resolution and at a data throughput of up to 2KHz. The data is logged directly to a Buffer memory and from there, at the end of each 109, it is dumped to an integral cassette data recorder. The recorded data can be transfered from the logger to a desk-top computer, via the IEEE 488 port, for further processing and display. All log parameters are user selectable by means of menu prompted keyboard entry and a Real-Time clock (RTC) provides date and time information automatically.
