The transverse analog feedback system of Hefei light source has been redeveloped. The new improved designs including beam position signal processing unit, DC-component signal removing unit, vector signal computing unit, etc, are described and new system’s commissioning results are discussed. The transverse coupled bunch instability at 200 MeV injection status is experimentally studied. The results show that, the injection damping rate is improved from 1.22 ms to 0.16 ms and the remnant beta oscillation can be suppressed.
