Abstract
In a digital oscilloscope, a sharp and fine line can be displayed at high horizontal resolution. The digital oscilloscope includes a memory for storing waveform data to be displayed; a display data output unit including sync signal generating unit for generating a sync signal and an output unit for reading the waveform data from the memory in synchronism with the sync signal to output said read waveform data; and an audio/visual color dot matrix plane display device including a display unit having dots arranged in a matrix form for color representation. The scan clock signal generator generating the scan clock signal in synchronism with the sync signal produced from sync signal generating unit, and the dot scan control unit sequentially supplying the display data outputted from the output unit in synchronism with the scanning clock signal to the dots of the display unit, whereby the content of the waveform data is displayed on the display unit.
