• For the Alarm trigger type: The scan sweep is triggered by an alarm that has
tripped. To do this, select the Alarm trigger type in the test setup and assign a
channel to be a trigger. When the scan is started, the Product automatically starts
to monitor the channel set as the trigger for a tripped alarm. Once an alarm is
tripped, the scan sweep starts and runs as directed by the test setup. Scan sweeps
will continue as long as the alarm is tripped. If the alarm is no longer tripped, the
Product will finish the scan in progress then wait for next alarm trip.
