When you select the type Timeout, the instrument will trigger if a pulse

occur when, depending on the polarity that you select, the signal stays higher or
stays lower than the trigger level for the timeout value. To set up for timeout
triggering, do the following procedures.
Stays High causes a trigger if the signal stays
higher than the trigger level for longer than the
timeout value.
Stays Low causes a trigger if the signal stays lower
than the trigger level for longer than the timeout
value.
