Event Sequence
When the time interval between event 1 occurring and the first occurrence of event
2 meets the specified time condition. If the condition is not met, the DL9000 ignores
event 2 that occurred and activates a trigger on event 2 that occurs while the specified
time conditions are met.
The following shows More than as an example.

Trigger Mode ►For the procedure, see section 6.1
Sets the conditions for updating the displayed waveforms. The following five trigger
modes are available.
Auto Mode
If a trigger is not activated within a specified time (approximately 100 ms, referred to as
the timeout time), the displayed waveforms are automatically updated.
Auto Level Mode
The displayed waveforms are updated in the same way as in auto mode.
In the case of an Edge trigger, if the trigger is not activated when the timeout time
has elapsed, the amplitude of the trigger source is detected, and the trigger level is
automatically updated to the center value of the amplitude.
Normal Mode
The displayed waveforms are updated only when the trigger condition holds. The
displayed waveforms are not updated if a trigger does not occur.
Single Mode
When the trigger condition holds, the displayed waveforms are updated once only, and
signal acquisition is stopped. This mode is useful when you are observing a single-shot
signal.
N Single Mode
The DL9000 acquires signals to different memory areas each time the trigger condition is
met for the specified number of counts. Then, the DL9000 stops acquisition and displays
the waveform of all acquired signals.
