由于原有计算机实测系列实验无论在硬件还是软件上都无法满足当今迅速发展的实验需求，故使用NI 数据采集卡和Labview 编程软件对软硬件进行了系统全面的现代化改造，解决了该系列实验中存在的一系列问题和不足，丰富了实验内容，增强了实验的趣味性和互动性，更好地达到了培养学生实验能力的教学目标.

Computer - aided data collection serial experiments are essential for students to better understand the Analog - to - Digital /Digital - to - Analog ( AD/DA) conversion. However，the instruments we used are outdated. By using Labview and corresponding data acquisition ( DAQ) card，the experiments are renovated and upgraded completely. The new designed instruments and software emphasize the cultivation of students' practical ability. New contents are also added to improve the learning interest of students and to better interact with them. The whole process is instructive to the renovation of similar university physics experiments.
