摘　　要：本文在简介VISA概念及特点基础上,叙述了在LabVIEW8.5开发环境下,利用VISA与仪器硬件接口无关的特性,以计算机为控制器实现与TDS3032B示波器的LAN、GPIB、RS232和Ag34410A数字电压表USB接口仪器进行通讯的控制方法,该方法简化了程序设计,对充分开发利用仪器本身的资源,避免因仪器具有的功能不去利用而造成的无形损失,读者可以直接利用程序中的原代码,减少程序设计中繁琐调试过程。经应用证明此方法简单实用,对灵活应用仪器程控功能和从事自动测试程序设计者具有参考借鉴价值。This paper introduced the basic concept and characteristic of VISA which was independent of the interfaces of the instruments, and mainly discussed the control of the TDS3032B oscilloscope via LAN,GPIB,RS232 and the control of the Ag34410A Digit Multimeter via USB interfaces using VISA in LabVIEWS. 5. The design of the program was simplified and the functions of the instruments were fully used by this means. Readers can use the original codes di- rectly without debugging. In practical applications, the method was not only helpful to use the program controlling function of the instruments, but also to the programmers who work on automatic measurement.
