Trigger Functions
External trigger
Processing starts when an external signal is input.
When the falling edge of a TTL level signal (minimum pulse 10 µs) is
detected, or when the input is shorted, triggering occurs.
Pretrigger
When triggering occurs, processing starts and includes the data from a
point preceding the current point by 1/8 frame time.
