An on-line data acquisition system of oscilloscope-embedded input/output controller for cavity BPM m

Cavity beam position monitor (BPM) is widely used in a precise electron beam position measurement.Based on high performance oscilloscope-embedded EPICS input/output controller,we developed an on-line cavity BPM signal processing system for fast data acquisition solution when designing a cavity BPM.Also,methods for extracting the position information from cavity pickup signals and calibration algorithm are included in this solution.
