3.15 : Trigger on slope
To set up a slope trigger, also define the physical channel and associated measurement to which you wish to
apply the recording condition
(1).
Choose slope
(2)
. The "+" or "-" sign in front of the amplitude value defines the
direction of the slope
(3)
. In the example above, if the "voltage" measurement on channel 1 increases by more
than 3V over a maximum sliding time window of 500ms
(4),
then the trigger condition is validated.
3.7.5
Trigger on window (avalaible in a later version)
To set up a window trigger, also define the physical channel and associated measurement to which you wish to
apply the recording condition
(1).
Choose window
(2).
Combination of trigger conditions
It is possible to combine several conditions on several channels which, once verified, will start/stop recording.
When several conditions are set, the user selects the "AND" or "OR" connector :
• AND : All defined conditions must be true simultaneously for recording to start/stop.
• OR : At least one of the defined conditions must be true for recording to start/stop.
ò
The set of conditions can include both analog and digital channels (in a later version). It is also
possible to have two different conditions on two measurements of the same physical channel.
Trigger and stop conditions can be set independently.
