•
When External Input is used as the trigger source, no stop trigger is accepted for 50 ms after capture is
started.
•
When the start trigger is External Input, data is captured at sampling intervals (fixed to 5 seconds if they
are more than 5 seconds) and retained temporarily.
This retained data is refreshed at sampling intervals (fixed to 5 seconds if they are more than 5 seconds).
Since the external trigger input operation conducts detection at 10 ms intervals asynchronously from
sampling, the retained data becomes the first point when an external trigger is detected. Starting from
this point, data is captured at sampling intervals.
•
Even when the stop trigger is sent from an external device, the detection is executed in 10 ms. The data
capture is stopped when the stop trigger is received.
