  • Page 53: Sample Rate

    Waveform Confusion: when the sample rate is lower than twice the actual signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt from the sample data is lower than the actual signal frequency. The most common aliasing is the jitter on fast edge. SMO1000E/SMO1000U 53/234...

  • Page 54: Oscilloscope Bandwidth And Sample Rate

    However, digital signals have frequency components above the fundamental frequency (square waves are made up of sine waves at the fundamental frequency and an infinite number of odd harmonics), and typically, for 500 MHz bandwidths and below, oscilloscopes have a Gaussian frequency response.
