基于HPI/O库的虚拟仪器与实验平台

The Virtual Instruments and the Lab Workshop Based on HP I/O Libraries

本章阐述了虚拟仪器的含义、特点、应用范围 ,并系统地介绍了如何在 HP I/ O库的基础上采用 IEEE- 488GPIB标准实现仪器和计算机的数据通讯 ,进而建立 HP虚拟仪器实验平台 ,文章最后结合一个实际的开关电源测试实例来说明该虚拟仪器测试平台的操作、使用及结果显示。

This paper presents the meaning, the characteristic an d the application of the virtual instruments. Then authors introduce how to use the standard of IEEE488 GPIB to establish the connection among the virtual instr uments and the computer based on the HP I/O Libraries, so the lab workshop can b e set up. At last, a practical switch power supply will be test to show the oper ation of the virtual instruments in the HP virtual instrument workshop.
