摘要
介绍了基于USB2.0的数据采集卡的设计与实现,并运用该数据采集卡组成信号发生/采集设备,成功开发了虚拟示波器、频谱分析仪。借助计算机的强大控制、计算能力,使测试系统可提供面向用户接口、面向总线接口和面向数据处理的虚拟仪器功能。
This paper introduces the design of a data acquisition device based on USB2.0 interface, and uses this device as a signal generating / acquisition equipment to develop the virtual instruments like oscillograph and frequency spectrum analyzer. The powerful compute and control ability of computer can help the testing system to face user interface, bus interface and data processing.
