本文论述了新一代仪器总线LXI的产生背景、发展概况和产品优势等等。鉴于B类LXI仪器灵活的特点,本文随后着重介绍了B类仪器所采用的IEEE1588时间协议同步原理,提出了几种能有效提高同步精度的方法,并给出基于DP83640的LXI_B类仪器实现方案。
This article discusses the background of a new generation of instrument bus LXI, development overview and product advantages and so on. In view of the flexible characteristics of Class B LXI instruments, this paper focuses on the introduction of IEEE1588 time protocol synchronization principle used in Class B instruments. Several methods to improve the synchronization accuracy are proposed. The realization of LXI_B class instruments based on DP83640 is also given.
