instrument is filling the pre-trigger memory.
You can choose whether the instrument is triggered when the trigger condition is satisfied while the instrument
is filling the pre-trigger memory.

certain period has elapsed (while the instrument is filling the pre-trigger memory).

When the instrument is triggered while it is filling the pre-trigger memory, the length
of the data actually recorded may be shorter than the specified recording length. (In
this case, the pre-trigger recording length is shortened. The recording length after a
trigger is calculated by subtracting the specified pre-trigger length from the specified
recording length.)
