  • Waveform display apparatus for easily realizing high-definition waveform observation
    Patent number: 5519820
    Abstract: A measurement unit U100 measures an input signal to be measured by sweeping frequencies in a measurement range having a predetermined frequency band so as to obtain waveform data to be developed on the frequency axis such as spectrum data in, e.g., a spectrum analyzer. The waveform data obtained by the measurement of the measurement unit U100 is displayed by a display device 500 via a display data processor U20 included in a control unit U200 to be described later to be developed on the frequency axis of the display device, i.e., in correspondence with the measurement frequencies.
    Type: Grant
    Filed: February 8, 1995
    Date of Patent: May 21, 1996
    Assignee: Anritsu Corporation
    Inventors: Takehiko Kawauchi, Yoshifumi Imazu, Katsuhiko Kamiyama, Mitsuyoshi Takano, Katsuhisa Iiyoshi, Takahiro Wada, Aiichi Katayama
