	A fully functional beam diagnostics system has been developed at SSRF serving user operation and machine study since 2009. Global orbit disturbances, BPM failures and DCCT noise signal have been observed randomly. Without correct event trigger it is hard to capture real time data and analyze the cause of the above failures. A BI global data warehouse has been implemented as a solution to buffer online data and do correlation analyze at SSRF.

To be a part of beam diagnostics system in SSRF 3.5 GeV electron storage ring, a high performance oscilloscope is introduced to build a bunch by bunch data acquisition and processing dedicated system, which is mainly used to observe individual bunch position in transverse plane and bunch charge. By analysis of Betatron oscillation amplitude distribution and corresponding filling pattern, we hope to find phenomenon about multi-bunch Wakefield effect[1] on beam Betatron oscillation for beam instability research.
