Method of operating an oscilloscope

An oscilloscope that is capable of displaying simultaneously multiple waveforms representing time evolution of a signal during respective acquisition intervals, said oscilloscope comprising:

• an acquisition means for acquiring waveform data using a first set of acquisition parameters,
• a display means for generating a display based on the waveform data acquired by the acquisition means,
• a user control means that can be used in the event that the display generated by the display means includes a waveform that is visually distinct from other displayed waveforms to select a feature within the displayed waveforms that distinguishes the visually distinct waveform from other displayed waveforms, and
• an oscilloscope control means for automatically deriving a second set of acquisition parameters that discriminate between the selected feature and other features of the displayed waveforms, and for supplying the second set of acquisition parameters to the acquisition means, whereby the acquisition means can acquire waveform data using the second set of acquisition parameters and the display means can generate a display based on the waveform data acquired by the acquisition means using the second set of acquisition parameters.
