The trigger wait time is the minimum time between the A and B
triggers. The trigger wait time is not the same as the horizontal delay
time. You can use the horizontal delay function to delay acquisition
relative to any trigger event, whether it is from the A trigger alone or
from a trigger setup that involves both the A and B triggers.
