4. Pre-trigger/Delayed Trigger: Data sampled before/after triggering.
The trigger position is typically set at the horizontal center of the screen. In this
case, you are able to view 6 divisions of pre-trigger and delayed information.
Adjusting the horizontal position of the waveform allows you to see more pre-trigger
information. By observing pre-trigger data, you can see the waveform before trigger
occurs. For example, you can detect the glitch that occurs when the circuitry starts.
Observation and analysis of trigger data can help you identify the cause of glitch.
