In this paper, the relationship between frequency f, decay factor λ and clipping of response waveform has been derived by analyzing the calibration process, principle of the Data Collector-Seismometer system and amplitude-frequency response characteristics, to solve the clipping problem of response waveform when conducting a sine calibration on Data Collector EDAS-24GN6 and Borehole Broadband Seismometer GL-S120B system. The results show that in order to avoid the clipping problem of response waveform, the product of frequency f and decay factor λ should be at least greater than the lower limit of 50.93 in the flat response frequency band of GL-S120B. However, in the decay response frequency band, the minimum value of the product is also reduced accordingly for the decay of voltage sensitivity. After the correction of decay factor, sine calibration of GL-S120B is conducted for the second time accordingly. The calculation results of calibration show that no clipping of the response waveform occurred and the amplitude-frequency response characteristics of its three-component are relatively consistent, with the change rate of voltage sensitivity to factory value within 5%. The conclusions of this study can provide frequency points parameters for sine calibration of stations using EDAS-24GN6 and GL-S120B seismic systems, and provide analytical basis for solving the clipping problem of sine calibration response waveform.
