摘　　要：虚拟数字示波器是由计算机、外围信号采集接口电路及相应的控制软件组成的 ,它可以根据需要只要改变软件就可以改变仪器的功能 ,开发时间短 ,功能灵活。虚拟数字示波器需要驱动程序才能使外围设备工作。驱动程序包括函数设计部分和软面板设计部分。本文以Agilent公司的 5 4 6 2 2D示波器为实际对象 。The virtual digital oscillograph is composed of computer, peripheral data acquisition interface circuit and the relevant control software. The oscillograph's function can be changed easily only by changing the control software . The virtual digital oscillograph must have driver program in order to make the peripheral equipment work. The driver program design is made up of the function design part and the softpanel design part. In this paper, the function design part and the softpanel design part of the driver program are based on the 54622D oscillograph in detail. It is realized to control and manage the oscillograph flexibly.
