【摘要】 分析IVI Driver的分类及IVI的体系结构,说明IVI驱动器的三个主要技术特征,即硬件无关性、状态缓存机制和仪器仿真功能。讨论了IVI Driver技术中类驱动器的作用,特别对动态链接库调用方式的选择和类驱动器影射方法的实现进行了研究,提出不修改用户测试程序,对类仪器前缀和特定仪器前缀进行替换,最终实现仪器互换。同时给出实现类驱动器的一般方法,并进行了实验验证。更多还原

【Abstract】 Based on the IVI driver architecture specification, the main technical features of IVI instrument driveris analyzed at first, that is hardware independence, instrument state caching and simulation, then the mechanismfor managing instrument attributes is researched. At last, a method of realizing a IVI class instrument driver isproposed. The result of experiments validated the feasibility of this method.更多还原
