Triggers
If communications are disrupted, the instrument cannot acquire data from wireless modules. In that
case, the instrument will not check whether the trigger conditions are satised for the channels of
such modules.
After the communications recover, the system will recover data and check whether the trigger
conditions are satised.
Data points acquired after the point when the stop trigger condition was satised will be regarded
as NO DATA.
The pre-trigger function will be disabled for data recovered after communications recovered.
Example: stop trigger (slope: [↑], trigger condition: [AND])
