  • Digital oscilloscope using color plane display device and data display method therefore
    Patent number: 5668469
    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.

  • Oscilloscope casing structure
    Patent number: 5629615
    Abstract: An oscilloscope of the following type is disclosed. Even though a main unit of the oscilloscope is horizontally placed, a display can be adjusted at an optimal angle. Also, while the main unit remains in such a position, press buttons can be depressed stably. An operating section is covered in the case of carrying the oscilloscope and knobs of the operating section, and the like, can be kept out of the way, thereby not hampering portability. An oscilloscope casing is divided into a display section and an operating section. A part of the top surface of the main unit is lowered and the operating section is placed on the lowered surface. The display section doubles as a cover for the operating section and is pivotally fixed to the top surface of the main unit via a hinge so as to freely open and close. The display section has a display screen inside and forms the top surface of the main unit and covers the operating section outside when the display section is closed.
