摘要
本文介绍了虚拟仪器的GPIB总线接口技术。计算机通过GPIB接口卡控制带有GPIB总线接口的电流源和电压表,构成了I^V曲线虚拟仪器测试系统。在Labview环境下完成了虚拟仪器前面板以及后台框图程序的设计,与硬件系统一起完成虚拟仪器的测试任务。
In this paper, we introduced the technique of GPIB bus interface. Through the controlling of the GPIB interface board, the computer controlled the current source and the voltmeter, both of which have GPIB bus interface, and a virtual instrument testing system for I^V curve was composed. The virtual instrument front panel and the background graphical control program in Labview environment accomplish virtual instrument testing task along with the hardware system.
