For the observation and study of transverse instability affected by insertion device and TFB, sets of an in-vacuum undulator narrow gap setting and TFB gain setting were operated in a beam-based experiment. A bunch-by-bunch (BYB) position on-line DAQ system was employed in the measurement to characterize frequencies of individual bunches. Bunch-train transverse oscillation amplitude variation were curved by harmonic analysis. In this paper, we will introduce the BTB ADQ system, and report on the measurement experiment and related data analysis.
