  For traveling wave accelerating structures, the tuning method assisted by bead pull technique based on non-resonant perturbation field distribution measurement has been widely applied for measure and tuning both constant-impedance and constant-gradient structures. The method is also suitable for deflecting structures, but some key considerations of the field component and of the bead are discussed. The measurement and tuning method will be used on new X-band deflecting cavity at SINAP, and the measurement on S-band traveling wave deflecting cavity is presented at last.
