摘要
本文介绍了VISA的开发目的、内部结构特点、分布式系统支持原理,从VISA的内部属性、软件兼容性和增强功能、硬件支持能力等几方面分析了VISA的特性,阐述了VISA作为I/O软件标准,为软件工具化提供了单一多厂家基础的可行性和科学性。
This paper introduce VISA'S goal,the distinguishing feature of internal architecture and the principle of distributed system support,analyzing VISA's character which is based on VISA's inside attributes software compatible capability. It set forth the feasibility and reasonability of VISA as I/O software standardization to provide a single multivendor foundation for instrumentation software.
