An oscilloscope in which an observer is freed from the troubles of triggering operations. Further, the processing speed of the oscilloscope is high, the number of errors is small, and it is also adequate to use a small memory capacity. Main period components included in a signal to be observed are extracted, waveforms regarding the extracted period components and information indicating with which period components the waveforms are triggered are displayed. The trigger can be varied to operate in response to other period components and the sweep time also can be varied.
