    The time needed to complete the final pre-trigger scan is part of the trigger latency; and so, in the pre/post- trigger mode, the trigger latency may be greatly increased. Not only do the trigger latency and jitter depend on the pre- vs post-trigger type of acquisition, they also depend on the trigger source: Software, digital (TTL), single-channel (Channel 1 analog), or multi-channel.
