  • Page 74: Taking Fft Measurements

    Application Examples Taking FFT Measurements You can take FFT measurements to determine if low-level distortion is present, or to find the source of noise in a mixed circuit. Detecting Distortion A pure sine wave can be input into an amplifier to measure distortion; any amplifier distortion will introduce harmonics in the amplifier output.
  • Page 75 Application Examples Identifying the Source of Noise Noise in mixed digital/analog circuits can be easily observed with an oscilloscope. However, identifying the sources of the observed noise can be difficult. The FFT waveform displays the frequency content of the noise. You may then be able to associate those frequencies with known system frequencies, such as system clocks, oscillators, read/write strobes, display signals, or switching power supplies.

  • Page 76: Triggering On A Video Signal

    Application Examples In the next figure, notice the component at 31 MHz (figure label 1). This coincides with a 31 MHz memory strobe signal in the example system. There is also a frequency component at 62 MHz (label 2), which is the second harmonic of the strobe signal.

  • Page 80: Capturing A Single-Shot Signal

    Application Examples Capturing a Single-Shot Signal The reliability of a reed relay in a piece of equipment has been poor and you need to investigate the problem. You suspect that the relay contacts arc when the relay opens. The fastest you can open and close the relay is about once per minute so you need to capture the voltage across the relay as a single-shot acquisition.
  • Page 81 Application Examples Optimizing the Acquisition The initial acquisition shows the relay contact beginning to open at the trigger point. This is followed by a large spikes that indicate contact bounce and inductance in the circuit. The inductance can cause contact arcing and premature relay failure.
  • Page 82 Application Examples Using the Horizontal Zoom Function If you want to take a close look at a particular spot on the acquired waveform, use the horizontal zoom function. To look closely at the point where the relay contact first begins to open, follow these steps: Push the zoom button Use the horizontal Position to place the expansion point close to where the relay contact begins to open.

  • Page 97 Reference WaveAlert Waveform Anomaly Detection. WaveAlert provides a way to detect when a waveform deviates from a steady-state condition. WaveAlert monitors the current waveform acquisition and compares it to the previous DPO waveform acquisitions, using a sensitivity value to adjust the comparison tolerance. If the current acquisition exceeds the comparison tolerance, the oscilloscope considers the current acquisition as an anomaly.
  • Page 98 Reference Use the general purpose knob to set the comparison sensitivity value. As signal noise and intensity levels affect the displayed waveform, you will need to experiment with the sensitivity setting to reduce the number of false anomalies due to signal noise. Use the Waveform Intensity front-panel button to adjust the persistence of the anomaly waveform.
