Setting external and timer triggers with the [AND] trigger source setting
In the following cases, triggering occurs in the same way as with the [Edge] set-
ting even when [Level] trigger detection is selected.
If logic trigger criteria have been met before an external or timer trigger is
applied, no triggering occurs. When external and timer trigger criteria have been
applied, and after they have been subsequently released, triggering occurs once
all trigger criteria are met again.
