| Abstract: | LXI class B module was introduced based on MCU according to the LXI class C in this paper. Since the precise clock synchronization technique based on IEEE1588 protocol was one of the key techniques of LXI, this technique used in LXI class B device was settled here. In order to improve the precision of clock synchronization, FPGA was used in the system to stamp time label for the data on network. Using this module, a traditional instrument can be upgraded into a LXI instrument which wa99s low cost and high-powered. |
