基于LXI总线的高速数据采集系统的研制

由已成为工业标准的以太网技术发展而来的LXI是解决下一代测试系统理想的解决方案,有必要对LXI仪器进行深入研究,文章介绍了LXI总线定义及其仪器分类,详细说明了高速数据采集系统及LXI总线传输模块的硬件组成、软件设计及在系统设计中需要注意的问题;且对在硬件设计中的电磁兼容问题做了简要的介绍。最后阐明了开发基于LXI总线的高速数据采集系统的重要意义和实际价值。

The Development of High Speed Data Acquisition System Based on LXI Bus

LXI is the next generation perfect test and measurement system which is developed from Ethernet technology which has become the industry standard,and more study is needed to make use of LXI instruments.In the paper,the definition of LXI Bus and the instrument types are introduced,and the high-speed DAS（data acquisition system）and the LXI bus transfer module hardware components,software design and system design issues that need to pay attention to are introduced in details.And in the hardware design of the electromagnetic compatibility issue the paper carries a brief introduction.Final results show that to development high speed data acquisition system based on LXI Bus has great significance and practical value.
