Chapter 6 Trigger System
89
When we set a specific trigger condition for a specific signal, especially when the time interval for satisfying the
trigger condition is long, we need to set the trigger mode to “ Normal ” so as to prevent the oscilloscope from
automatic forced trigger.
Figure 6-6 shows a conceptual demonstration of the acquisition memory. In order to understand the trigger event,
the acquisition memory can be divided into pre-trigger and post-trigger buffers. The position of the trigger event in
the acquisition memory is defined by the time reference point and trigger position (horizontal delay) settings.
Figure 6-6 Conceptual Demonstration of Acquisition Memory
All events displayed to the left of the trigger point occur before trigger. These events are called pre-trigger
messages that show events before the trigger point. All events to the right of the trigger point is called post-trigger
