Configuring the Pre-trigger and Post-trigger Settings
Difference between [Waiting for Pre-Trigger] and [Waiting for Trigger]
When starting a measurement, the instrument starts filling the pre-trigger memory. During this
period, the instrument displays the message [Waiting for Pre-Trigger] . After having filled the pre-
trigger memory, the instrument displays the message [Waiting for Trigger] until it is triggered.
While displaying [Waiting for Pre-Trigger] , the instrument is not triggered even when a trigger
condition is satisfied.
