Abstract
In a digital oscilloscope for indicating an input signal waveform on a display, all or part of the circuits which constitute the oscilloscope are de-energized in accordance with at least one of an operation mode in which the digital oscilloscope has been set by the user and another mode of the oscilloscope. Alternatively, it is determined whether the digital oscilloscope is not operated for a time established by the user or more, and if it is determined that the oscilloscope is not operated for the set time or above, the display is de-energized.
