| 1. | As a new bus standard in computer peripheral hardware , usb is adopted and widely used in virtual instruments for its ease of use , true plug and play , power supply from bus , high transmission speed , etc . the purpose of this project is to design and develop a virtual instrument that can test and display semiconductor transistor output characteristics curve , instead of tradition instrument which has being used in labs by now
而usb总线作为一种新兴的计算机外设总线标准,由于易用、支持热插拔、总线供电、传输速率高等特点,已经在虚拟仪器当中得到采纳与普及。本文介绍了一种实现晶体管特性曲线测量的虚拟测试仪器的设计和制作方案,其可用来取代目前在实验室中使用的老式的晶体管特性图示仪。 |
