分析PC数据采集系统能力的工具应该是高效益比的、容易使用的,如果需要数月时间建立和运行,同时要花费大量的投资用于购买设备,并且需要有专门的技术人员或对编程方法的深入理解,那么,这样的工具就不太适用。因此,根据以上的要求,我们不可能对数字化板的各个方面都进行分析,但对于那些对功能和误差产生重要影响的指标还是要进行重点分析。本文的第一部分着重介绍了最常用的计算机数据采集插入板的共模抑制测试问题;本文的第二部分则将重点放在混叠和建立时间的测试上,通过这部分的论述达到两个目的: 了解怎样对数字化板进行评估以达到选择合适的工作板的
Tools for analyzing the capabilities of a PC data acquisition system should be cost-effective and easy to use. If it takes months to build and run, it also costs a lot of investment to purchase equipment and requires a dedicated technician or programmer In-depth understanding, then, such a tool is not suitable. Therefore, based on the above requirements, it is impossible for us to analyze all aspects of digitizing board, but we still need to make a key analysis for those indexes that have a significant impact on function and error. The first part of this article focuses on the most commonly used computer data acquisition plug-in board common mode rejection test problem; the second part of this article will focus on the test of aliasing and set up time, through this part of the discussion for two purposes : Learn how to evaluate digital boards for the right job board
