Distributed Test System based on LXI Bus

LXI is a new modularization instruments platform standard for automation test system based on Ethernet LAN after GPIB, VXI, PXI instrumentation bus. A type of LXI Distributed test system architecture was given out based on the development of instrumentation bus, LXI bus system structure and main characteristics, then compared and analyzed Drive command triggering, Network news triggering, IEEE-1588 clock synchronization triggering and the LXI triggering bus four kinds of different synchronization test strategies, the appropriate choice may carry on according to the triggering accuracy requirements, test object far and near, the dispersion degree. Finally, the reliability of the system is further analyzed through the application examples of the system.
