Although there are about 200 electron BPMs installed in the storage ring, the beam-line managers or users prefer X-ray BPMs to monitor beam stability. Among the beam lines, different electronics are used to acquire data at various sampling rates. A method to calculate the beam intensity fluctuation within different frequency ranges is described in this report. The results of calculations are shown in the control system and saved in the archive system thus helping to monitor and analyse beam quality on- and off-line. Initial experiences with this system will be discussed in this report.
