- Page 22 Convenient functions What is a pre-trigger? It is a function which allows waveforms before the trigger point to be recorded. Merit Useful to detect signs before abnormal occurrences happen because parts before the trigger point are recorded. If the pre-trigger If the pre-trigger is not used, only the parts after the trigger point are recorded.
