Abstract Vibrosesis is of increasingly important value in geological exploration. During the field work, different geological conditions need different parameters, the choice of suitable excitation parameters and the realization of the appropriate sweep signal become important problems. Main numbers of controlled seismic source, start-end frequency, scanning length, scanning slopes and its length in linear sweep signal, pseudo code order and carrier frequency in pseudo sweep signal were analyzed and discussed in this paper, and the influence of these parameters on quality of the sweep signal was studied in detail. The design of IP core of VSG hardware and the signaling system based on SOPC can meet the technical indices of the sweep signal.
