  • Page 272: Spectral Analysis Overview

    Math setups Spectral analysis overview windows provide better amplitude accuracy over frequency resolution. The choice of window also affects the resolution bandwidth. Gate Position moves the gate that selects the data for the spectral waveform. The gate position is the center point in the gate measured in seconds with respect to the trigger point.
  • Page 273 Math setups Spectral analysis features FFT windows The instrument allows you to match the optimum window to the signal you are analyzing. The Rectangular window is best for nonperiodic events such as transients, pulses, and single-sequence acquisitions. The Hamming, Hanning, and Blackman-Harris windows are better for periodic signals. The Kaiser Bessel window has less spectral leakage than the Hanning, Hamming, or Rectangular windows.
  • Page 274: Fft Process

    Math setups FFT process FFT process The FFT process mathematically converts the standard time-domain signal (repetitive or single-shot acquisition) into its frequency components. The FFT function processes the waveform record and displays the FFT frequency domain record, which contains the input signal frequency components from DC (0 Hz) to ½ the sample frequency (also called Nyquist frequency (see page 173)).
  • Page 275: Fft Windows

    Math setups FFT windows FFT windows The FFT process assumes that the part of the waveform record used for FFT analysis represents a repeating waveform that starts and ends at or near the same voltage of a cycle. In other words, it is an integer number of cycles. When a waveform starts and ends at the same amplitude, there are no artificial discontinuities in the signal shape, and both the frequency and amplitude information is accurate.

    Math setups Time domain gating Time domain gating You can use time domain gating to select a specific segment of your signal for spectral analysis. Two controls, gate position and gate duration, determine the location and size of the gate. The resulting spectrum corresponds to the frequency components of the signal in the gated segment.
  • Page 278: Aliasing

    Math setups Aliasing Aliasing Problems occur when the instrument acquires a signal containing frequency components that are higher in frequency than the Nyquist frequency (see page 173). The frequency components that are above the Nyquist frequency are under sampled and appear to "fold back" around the Nyquist frequency, showing as lower frequency components.

  • Page 701: Bandwidth Enhancement

    Oscilloscope Reference Bandwidth enhancement Bandwidth enhancement Bandwidth enhancement is a DSP implemented FIR filter that flattens the oscilloscope frequency response, and makes the phase response more linear. This results in better matching of channel responses and better signal fidelity. On some oscilloscope models, the bandwidth may be extended beyond what the analog channel exhibits, while other models provide no bandwidth extension but use the enhanced filter to reduce noise and provide better signal fidelity.
  • Page 702: Coupling

    Oscilloscope Reference Coupling Coupling All instruments and probes specify a maximum signal level. Do not exceed the limit, even momentarily, as the input channel or probe may be damaged. Use external attenuators if necessary to prevent exceeding the limits. Coupling determines whether an input signal is directly connected to the input channel (DC coupling), connected through a DC blocking capacitor (AC coupling), or not connected at all (GND coupling).

  • Page 704 Oscilloscope Reference Vertical Acquisition Window considerations The offset control subtracts a constant DC level from the input signal before the vertical scale factor is applied, and the vertical position control adds a constant number of divisions of signal after the scale factor is applied to the resulting difference.

This moves the vertical acquisition window up and down on the waveform. With input signals that are smaller than the window, it appears the waveform moves in the window. Actually, a larger signal shows what really happens: the offset moves the middle of the vertical acquisition window up and down on the input signal.
