摘　　要：利用LabVIEW软件并结合PCI-6024E数据采集卡设计了虚拟数字示波器.这种示波器充分利用了计算机的存储和与外部设备连接的能力,测量波形可以一次存储,长期保存,多次显示,便于观察单次变化过程和缓慢变化的信号,波形可以程控和多种方式输出,硬件具有开放性,可以通过修改和增加软件模块,来增加仪器的功能.图6,参8.The constituents and features of the virtual instruments were introduced in the paper. Based on that, a virtual digital oscilloscope was designed by use of the LabVIEW combined with PCI-6024E data-collecting card. This kind of oscilloscope sufficiently utilized the computer＇s memory power and capability of connecting with the external equipment. Once the measured shape of the wave was stored, it could be saved for a long time and be showed many times so that the signals which changed only once or changed slowly could be observed. The shape of the wave could be controlled by computer and be exported in several ways. The hardware of the oscilloscope had the opening ability. The function of the oscilloscope could be enhanced by modifying or adding the software module. 6figs., 8refs.
