Research on Synchronization and Triggering of LXI Bus

Abstract

With the development of the LXI technology, synchronization and triggering of LXI instruments has become hot topics in the research world. This paper analyzes five modes of LXI triggering. Combined with Trigger Response Times and Trigger Output Response Times mentioned in LXI Device Specification (Revision1.4), it elaborates the significance of LXI instruments synchronization via LXI Class A and Class B instrument synchronization accuracy test. Besides, taking LXI A logic analyzer for example, it introduces the implementation of LXI trigger interface in detail. According to the result of the LXI instrument clock synchronization experiment, the instruments can synchronize to each other with good precision.
