Abstract

The present invention provides a method and system for oscilloscope triggering. The power spectrum entropy threshold Gp and the singular spectrum entropy threshold Gs are obtained by calculating the averages of the power spectrum entropy Hi and the singular spectrum entropy Ei of the first a waveform data frames respectively. Then, for the waveform data frame xa+1(τ) and thereafter, If the power spectrum entropy Hi is greater than power spectrum entropy threshold Gp and the singular spectrum entropy Ei is greater than the singular spectrum entropy threshold Gs, the waveform data frame xi(τ) is an abnormal signal, the second trigger occurs, storing and displaying the waveform data frame. Thus the storage and display of abnormal signal is realized.
