It allows you to capture periodic or random events with the full sample rate but to ignore all the dead time between events.  For each trigger it stores one sweep with a time stamp.  When you want to look at the record you can roll back through memory and look at each individual event with full resolution.

Yes, this was a tek..it does the same thing (called "fast frame" in 
their manual) and the trigger time stamps were actually high resolution 
(higher than the sample rate).
