Trigger Function
Triggers provide functionality for starting and stopping
measurement based on specific conditions and signals.
When a specific condition (a trigger condition) occurs, the
trigger is said to activate.
The points at which triggers activate (i.e., the points in time
at which trigger conditions are satisfied) are known as trigger
points, which are identified by the mark.
When a trigger activates, you can start or stop recording.
Trigger sources can be selected from among the following:
• Analog triggers (level, window)
• Pulse (level, window)
• Logic triggers (condition, pattern)
• Waveform calculation (level, window)
• Interval triggers
• External triggers
