摘要
文中介绍以Altrera公司FLEX10K器件为虚拟仪器核,辅之以少量必需的模拟与控制电路,组成一个多功能卡,在PC机控制下,在Windows95/98中借助Delphi5.0实现的人机界面,有效地实现频率计、多段存贮计时器、相位差计、数字IC块测试、单稳集成块测试等多种常用电子仪器功能的设计原理与实现方法。
In this paper, we describe a multifunction card, which used the FLEX10K device of Altera Company as the kernel of virtual electronic instrument, which was assisted with necessary analogue and control circuits. By means of Delphi 5. 0 we can realize man -computer interface in Windows95/98, the card controlled by PC can efficiently realize the function of many kinds of common electronic instruments such as frequency meter, multistage storage counter, phase difference meter, digital IC testing instrument, monostable IC testing instrument etc. The instruments' design principle and realizing method are also given.
