Bunch-by-bunch (BxB) beam current measurement is an important method to study filling pattern of injection and beam instability threshold for multi-bunch operation storage ring, also, necessary equipment for top-up injection. A high-speed high-precision ADC and FPGA are used to construct the bunch-by-bunch beam current measurement system. FPGA reads data from ADC, and transfer the data to PC via USB. A LabVIEW program is running on PC to process the data, and communicates with other accelerator equipment with EPICS by CA Lab. Besides the bunch-by-bunch beam current measurement, the BxB longitudinal tune is measured by the system, and other potential bunch-by-bunch beam diagnostics study could be done in future, like bunch-by-bunch beam life etc., to improve the performance of the storage ring of Hefei light source.
