摘要
为了弥补传统仪器功能单一、不易升级和携带不便的缺陷,本文利用NI USB-6211数据采集卡及LabVIEW软件,设计开发了一个虚拟信号发生系统,该系统除了能够生成正弦波、方波、三角波、锯齿波及多种噪声信号外,还能够生成脉冲信号、数字信号。实验结果表明,该系统具有很好的实用价值。
Owing to deficiencies in traditional instruments, such as the single function, difficulty in upgrade and inconvenience in carrying, we design and implement a virtual signal generator by taking NI USB-6211 as data acquisition card, and LabVIEW as software. The system can generate sine wave, square wave, triangle wave, saw tooth wave and various noise signals, as well as pulse signal and digital signal. Experiment results show that the system has good practical value.
