recording
Since the trigger stops the storage, all stored information is termed pre
-
trigger
information. When storage stops because the acquired signal has met a trigger
condition, only pre
-
trigger information is available
-
information recorded before
the signal met the trigger condition.

More often, one is interested in what happened just before and after the
condition was met. To achieve this aim, a delay is introduced. Once the trigger
condition is met, storage is stopped
-
not immediately, but only after a
programmable delay counter has counted out. The memory now contains pre
-
trigger information and post
-
trigger information.
