Abstract
Based on the introduction of developments of LXI instruments, LXI instrument synchronization problem and triggering principle of IEEE1588, the causes of the synchronization are analyzed. A new synchronization algorithm of frequency compensation is proposed. The algorithm is effective in dynamic compensation. It is suggested that the algorithm should be implemented with FPGA device. With Quatus II, the dynamic compensation of the local clock is simulated and its validation is proved in the experiments. Finally the hardware implement of the whole system scheme with the dynamic compensation algorithm is proposed.
