To Set up the Trigger System
The trigger determines when the oscilloscope starts to acquire data and display a
waveform. When a trigger is set up properly, it can convert unstable displays or blank
screens into meaningful waveforms.
When the oscilloscope starts to acquire a waveform, it collects enough data so that it
can draw the waveform to the left of the trigger point. The oscilloscope continues to
acquire data while waiting for the trigger condition to occur. After it detects a trigger,
the oscilloscope continues to acquire enough data so that it can draw the waveform
to the right of the trigger point.
