3.14 : Trigger on level
First define the physical channel and its associated measurement to which you want to apply the trigger condi-
tion
(1)
. Then describe the condition by selecting "level" in type, the ">" or "<" operation for the overshoot direction,
and the threshold value
(2)
. In the example above, recording will be triggered if the "voltage" measurement on
channel 1 exceeds 25V. It is possible to activate a duration on this condition. In this case, the user defines a
time delay during which the condition must remain true for the condition to be validated. In the example above,
exceeding the 25V threshold must last at least 1 second for recording to start/stop
(3).
ò
The filter prevents unwanted triggering caused by transient interference on the channel.
