Sub- topics of the subject is the \bus interface module and system control platform for data transmission technology. The multi-function instrument modules through the the LXI bus interface module and system control platform for the exchange of information and control platform control commands issued in accordance with the multi - function instrument system to perform the appropriate instrument function operation and data transmission . At the same time , can be realized through the the LXI bus interface module multi-functional network equipment . This paper through the analysis of domestic and international bus instrument development status , introduced the concept of the LXI bus instrument , further analysis of the characteristics and advantages of LXI bus instrument to clarify a the LXI bus in the future instrument bus status , reflects the importance of this subject and necessity. On this basis , we further analyzed the requirements of the project on the subject , identified as the papers focus the multifunction module developed LXI system digital multimeter , frequency counter , and high-speed data acquisition card and determine the technical indicators , the next article will be the more practical aspects of the various modules of measurement theory , system requirements, measurement solutions , and the feasibility of the schematic design, component selection and PCB layout , demonstrated in detail the method and process of the realization of the project . Multifunction instrument as a complete LXI bus , the paper discusses the measurement module on the the LXI bus communication module implementations also made a detailed exposition . Finally, the development of a system test program to verify the functionality of the module and the key indicators .
