Patent ID: 8788229

Claim:
A method for controlling a digital oscilloscope comprising a trace intensity calculator for generating intensity information of a waveform trace, a trace intensity synthesizer for generating accumulated intensity information according to the intensity information of the waveform trace generated by said trace intensity calculator, and a displaying means for displaying a waveform according to said accumulated intensity information; and said method including the steps of: a determining step for determining, by a controller, whether a time interval between trigger signals is larger than a predetermined threshold, turning to a static fluorescence processing step when said time interval between the trigger signals is equal to or less than the predetermined threshold, and otherwise turning to a dynamic fluorescence processing step; the static fluorescence processing step for accumulating the intensity information of a plurality of waveform traces generated by said trace intensity calculator to generate the accumulated intensity information corresponding to a static fluorescence effect; and the dynamic fluorescence processing step for attenuating old accumulated intensity information and accumulating the intensity information of the waveform trace newly generated by said trace intensity calculator on the basis of the attenuated accumulated intensity information to generate new accumulated intensity information corresponding to a dynamic fluorescence effect.
