TRIGger Commands

Trigger system makes the meaningful waveform shown steadily. Trigger determines
when the oscilloscope starts to acquire data and to display a waveform. When trigger
is set up properly, it can convert unstable displays into meaningful waveforms.
When the oscilloscope starts to acquire data, firstly enough data are needed to be
collected so as to shape into a waveform on the left of the trigger point. The
oscilloscope continues acquiring 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 display the waveform on the right of the trigger point.
Trigger Mode includes: Edge, Pulse, Video, Pattern and Alternation trigger.
