Measurement of the bunch-by-bunch particle beam position related to dynamic instability is a useful input to accelerator optimization. And the bunch-by-bunch information has been contained in the BPM signals, including bunch charge, transverse position and longitudinal phase information. This paper reports a 3D beam position monitor system based on a high speed digital oscilloscope, which has been used to capture three-dimensional position information during the injection transient at the Shanghai Synchrotron Radiation Facility. With this information the traces of stored bunch and refilled bunch, and the mismatch of energy, transverse position and longitudinal phase between them can be precisely retrieved. The progress of this work and several particular experimental results will be discussed in this paper. The details of data processing method so-called software re-sampling technique will be discussed as well.
