Abstract: A cold model measurement system of the RFQ resonant cavity is introduced, which can measure the field distribution of cold model through bead-pull measurement. The system has two advantages. One is that people can write a script and make it automatically accomplish all the procedures, including pulling and positioning the bead and all the data acquisition. The other is that the precision of bead positioning is improved much by using the step-motor. Some measurement results of a D+ RFQ cold model are given.
