Triggering
6.15 Setting the Timer Trigger
Function
The trigger is activated at specified time intervals from the specified time. The following time
intervals are selectable.
Trigger position
As in the normal trigger, you can set the trigger position to observe the phenomenon occurring
around the specified time. Initially, the trigger position is set to 50% and positioned at the
center of the screen. To observe only the waveform after the trigger set the trigger position to
0%. To observe only the waveform before the trigger set it to 100%.
Notes on Timer Trigger
• Depending on the time interval setting, a trigger may occur while the waveform is being
acquired or during the pre-trigger period (a preparation period for observing the waveform
before the trigger time). In this case, the trigger is ignored.
• If the trigger time is set to a time in the past, the trigger is activated when the current time
becomes:
Specified time + time interval
×
N (where N is an integer).
• If you specify the acquisition count, the waveforms are acquired the specified number of
times. If it is set to Infinite, the waveforms are acquired until the
STOP
key is pressed. For
setting the acquisition count, see page 7-3.
• You can save the waveform to the floppy disk, make a hard copy, and do other operations by
using the action on trigger function.
