The invention relates to a method of the dynamic characteristic traceability calibration of a high-pressure transducer, and calibration equipment, belonging to the technical field of pressure transducer. The method is as follows: exerting a static pressure on a high-pressure transducer to be calibrated, for realizing a frequency area to be zero frequency traceability calibration; on the basis, exerting an ultra-short pulse motivating pressure, testing the frequency responding characteristic of the high-pressure transducer through a test or a metrologic instrument. The method has the advantages that the method uses a common hydraulic pressure calibration method to realize the dynamic characteristic traceability calibration of the high-pressure transducer; because of adopting a pre-exerting static pressure processing method, the reversed pressure received by the transducer to be tested is reduced, thus effectively protecting the expensive transducer, and the frequency service range of the calibration method is
