Abstract
The present invention provides a method and system for oscilloscope triggering. The power spectrum entropy threshold Gand the singular spectrum entropy threshold Gare obtained by calculating the averages of the power spectrum entropy Hand the singular spectrum entropy Eof the first a waveform data frames respectively. Then, for the waveform data frame x(τ) and thereafter, If the power spectrum entropy His greater than power spectrum entropy threshold Gand the singular spectrum entropy Eis greater than the singular spectrum entropy threshold G, the waveform data frame x(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.
