The design of VXIbus DMM module

Abstract

A design method of DMM module adhered to VXIbus which is the latest measurement and test instrumentation bus is given in this paper. Using MCS-51 monolithic microcomputer as controller, dual-RAM as configuration and communication registers, the module is designed as a message based B-size module. The module has been applied to an automatic test system for radar. The design method is also available to other VXIbus instruments.<>
