In this paper, the relations between resolution and working frequencies of two cavities are given by mathematical deduction. The laws of resolution change caused by some decisive factors such as beam position, working frequency, electromagnetic mode and probe position are obtained through simulation on computer. An improved measurement method utilizing TM020 mode is presented based on the theory above. The simulation results show that the improved method can enhance the resolution capability of the bunch length monitor and these analyses can provide references for the design of cavity bunch length monitor.
