ABSTRACT:
In an oscilloscope having a video signal input, a video signal and the like can be monitored in addition to the normal waveform monitoring operation as the oscilloscope. The oscilloscope having such a video signal input is arranged by a first input terminal for the oscilloscope, for entering therein a signal under monitor; an oscilloscope unit connected to the first input terminal, for processing the signal under monitor supplied from the first input terminal to output an oscilloscope signal; a second input terminal for entering therein a video signal; a picture monitor unit connected to the second input terminal, for processing therein the video signal supplied from the second input terminal to output a picture monitor signal; a display switching unit for selecting one of the oscilloscope signal derived from the oscilloscope unit and the picture monitor signal derived from the picture monitor unit; and a display device for displaying therein either the oscilloscope signal or the picture monitor signal derived from said display selecting unit.
