In order to correct the field frequency deviation caused by the machining error and the welding shrinkage in the manufacturing process of the multi-cell medium β SRF cavity, a regulating mechanism-warm tuner is designed based on the multicell medium β SRF cavity's characteristics and the field flatness principle. The tuner contains five parts, which are the activity carriage, the gearbox carriage, the tailstock, the activity tailstock and the bed body. The warm tuner is used in the test of the field flatness and the field frequency of a medium β SRF cavity. Finally, the test system of the RF superconducting cavity field flatness is set, detailed analyses and designs of the bead-pulling system, the network analyzer and the microcomputer control system are carried out. The microcomputer control system uses the virtual instrument Lab VIEW software as the platform to control the other parts in the test system, and to analyze the test results, to present the test results. The results show that the medium β SRF cavity warm tuner can be successfully used for the test and modulation.
