The invention provides a power-frequency synchronization depth storage ns-grade pulse multi-parameter generation system, comprising a computer, a waveform storage module in electric connection with the computer, a numerical-control pulse signal generation module and a power-frequency synchronization trigger module, wherein the numerical-control pulse signal generation module and the power-frequency synchronization trigger module are electrically connected with the waveform storage module, and the power-frequency synchronization trigger module is electrically connected with the numerical-control pulse signal generation module. By means of the power-frequency synchronization depth storage ns-grade pulse multi-parameter generation system of the invention, pulse amplitude, pulse rising time, pulse fall time, pulse polarity, the number of pulses, pulse repetition frequency and pulse trigger phase are set via the computer, and the power-frequency synchronization trigger module is further controlled to trigger the numerical-control pulse signal generation module at the set phase, thereby realizing power-frequency synchronization, standard pulse generation, low cost and high convenience and efficiency. The precision of signal output is guaranteed, complicated control-panel operation is avoided, and the problem of the prior art of single function is solved.
