Edge Qualified and Wait: Trigger after timeout. The broken upward-pointing arrows indicate potential triggers,
while the bold ones show where the actual triggers occur.
Qualified First Trigger
Qualified First trigger is intended to be used exclusively in Sequence Mode to speed up the
trigger rate. With Qualified First trigger, a single valid trigger is sufficient to acquire a full
sequence. Other than in Sequence Mode, Qualified First is identical to the Qualified triggers.
In data storage applications, the index pulse can be defined as the qualifier signal and the servo
gate signal as the trigger source.
