Abstract: Fabry-Perot Interferometers has been more and more widely used in China's astronomical community. At present, the Fuxian Lake Solar Observatory at the Yunnan Observatory has purchased two FPI for use in the spectral observation of the 1m new vacuum solar telescope. As the domestic research on FPI is still relatively small, overseas inquiries to relevant information is not yet. Therefore, understanding its control system is not only the need to research FPI, but also the necessary foundation in daily work. In this paper, a basic review of FPI control system is given, and describes the digitalization of research on AD Converter Accuracy Requirements of Digital Front End of Control System. Calculate the accuracy of the F-P parallel board control and finally select the AD converter that meets the requirements.
