• EEVblog #601 – Why Digital Oscilloscopes Appear Noisy


    Why do digital oscilloscopes appear noisier than traditional analog oscilloscopes?
    Dave busts the myth that digital scopes are noiser than analog scopes, and demonstrates what inherent advantages digital scopes can have over analog scopes in terms of true waveform capture. And also why your analog scope may be hiding important signal detail from you.
    Demonstrations of how memory depth, analog bandwidth, averaging, and intensity graded displays can all effect the signal detail you see on your digital oscilloscope.
    And how long exposure camera shots on analog oscilloscopes can reveal detail you can’t see with your eyes.

    Demonstrations are done on the new Tektronix MDO3000, the Rigol DS1052E, the Tektronix TDS220, and Tektronix 2225 analog oscilloscope.
