Universal measurement system controller

Abstract

This thesis describes the design and implementation of a measurement instrumentation system controller by using IEEE 488 standard bus (IEEE 488 is also called GPIB General Purpose Interface Bus, within the thesis we will use GPIB instead of IEEE 488) named as UMSC (Universal Measurement System Controller). GPIB is a widely used digital communication standard in instrumentation. The most famous companies manufacture their instruments with GPIB. They can be interconnected by using GPIB, in order to realize the complex test sets. At that point, a controller is needed to control the communication between them. However the controllers mentioned above are very expensive devices. If you need one or more small test sets with remote control, using them is not feasible economically. So dedicated small controllers are necessary. The aim of this work is to satisfy this requirement. The UMSC is designed as a microprocessor-based system. It utilizes the GPIB talker, listener and controller, functions. It is a programmable device, to realize special test algorithms. It provides a line editor to edit user programs, and a compiler to check the syntax of the user programs and to interpret them. It also offers a basic language developed for this work to write user programs.
