【摘要】 高昂的价格阻碍了数字存储示波器在生产和试验中广泛的应用,数据采集卡和PC机的结合并利用PC机强大的硬件和软件资源降低数字存储示波器的价格,但繁琐的开机箱和插卡的操作仍对不熟悉PC机硬件技术的人员产生困难。独立于PC机的但通过PC机增强性并口EPP与PC机连接的虚拟数字存储示波器不但利用PC机强大的硬件和软件资源降低了数字存储示波器的价格,也因为它简便的连接方式为其推广应用提供了条件。更多还原

【Abstract】 The oscilloscope digital storage(DSO)is hindered to apply wildly in our production and test by high price.The combination of the data acquisition card and PC reduce the price by PC’s the hardware and software resources.But the complex operation of opening PC’s carver and inserting the card also make the technician difficult using the data acquisi-tion card.The virtual instrument of oscilloscope digital storage which separated with PC and connected PC via enhenced parallel port also reduce the price by PC’s the hardware and software resource.It provide the possible using the oscilloscope digital storage wildly as easy operation of connecting with PC.更多还原
