Resonantly coupled RFQ is commonly used as the low energy accelerating structure for an intense beam proton linac. It is essential that the field distribution meets the design requirement in order to minimize the beam losses. Based on the RFQ transmission line model, a study on the field tuning was conducted on the cold model RFQ, focusing on the characteristics of the resonantly coupled RFQ structure. A satisfactory result was achieved in the field stabilization, and it also demonstrated the validity of the RFQ tuning code on the platform of LabVIEW.
