  • Page 101: Trigger And Trigger Adjustment

    5.1 Trigger and Trigger Adjustment What is Trigger? The oscilloscope can capture a waveform only when it meets a preset condition first. This action of capturing the waveform according to the condition is Trigger. The so-called capture waveform is that the oscilloscope grabs a signal and displays it.

  • Page 104 Chapter 5 Trigger System What is Forced Trigger? When the oscilloscope does not meet the trigger condition, the artificial or automatic oscilloscope trigger is the forced trigger. It means that the oscilloscope only grabs a signal segment for display regardless of whether the condition is met or not.
  • Page 105 Figure 5-5 Oscilloscope Trigger Mode Setting If a signal feature is not understood, the oscilloscope should be set as “Auto” mode, which can ensure that the oscilloscope can also display the waveform when other trigger settings are not correct. Although the waveform is not necessarily stable, it can provide the intuitive judgment for our further adjustment of the oscilloscope.
  • Page 106 Chapter 5 Trigger System When we set a specific trigger condition for a specific signal, especially when the time interval for satisfying the trigger condition is long, we need to set the trigger mode to “Normal” so as to prevent the oscilloscope from automatic forced trigger.

During hold-off time, the oscilloscope does not re-trigger until the end of the hold-off time, and the hold-off time can be used to stably trigger complex waveforms.

Sampling principle According to the Nyquist sampling principle, for a bandwidth-limited signal with the maximum frequency f , the...
  • Page 223 Figure 10-1 Aliasing Oscilloscope bandwidth and sampling rate The oscilloscope bandwidth usually refers to the lowest frequency at which the input signal sine wave is attenuated by 3dB (-30% amplitude error). For oscilloscope bandwidth, according to the sampling principle, the required sampling rate is f .
  • Page 224 Chapter 10 Sampling System Frequency Figure 10-2 Theoretical Brick-Wall Frequency Response However, digital signals have frequency components that exceed the fundamental frequency (the square wave consists of sine waves at fundamental frequency and an infinite number of odd harmonics), and for bandwidths of 500MHz and below, the oscilloscope typically has Gaussian frequency response.
  • Page 225 Aliasing Frequency Figure 10-3 Sampling Rate and Oscilloscope Bandwidth The oscilloscope bandwidth is limited to 1/4 sampling frequency and reduces the frequency response above the Nyquist frequency. ≥4f Therefore, in fact, the oscilloscope sampling rate should be 4 times or more of its bandwidth: f .
  • Page 226 Chapter 10 Sampling System Oscilloscope rise time The oscilloscope rise time is closely related to its bandwidth. The rise time of an oscilloscope with Gaussian type frequency response is approximately 0.35/f (based on the standard from 10% to 90%). The oscilloscope rise time is not the fastest edge speed that an oscilloscope can accurately measure. It is the fastest edge speed that the oscilloscope can produce.
  • Page 227 According to Dr. Howard W. Johnson’s book “High-Speed Digital Design–A Handbook of Black Magic”, all fast edges have wirelessly continuous frequency components. However, there is a turning point (or “inflection point”) in the fast edge spectrum at which frequency components above f are negligible in determining the knee signal shape.
