Acquisition Triggering > Function
Used to set acquisition triggering conditions (such as level, slope, and number of pre- and post-trigger data points) that define the “trigger” or starting point for data acquisition to disk. When recording is initiated, data acquisition to disk will begin only when the trigger (i.e., that point on the waveform that corresponds to the level and slope you specified) is detected.
This function should not be confused with the Oscilloscope Mode function. Although both deal with triggering, this function sets triggering conditions for acquiring data to disk. The Oscilloscope Mode function sets triggering conditions for displaying the waveform on your monitor (see also Display Mode Selection).
