TRIGger Commands

To make the waveform display more stable, trigger system needs to be set. The
trigger determines when the oscilloscope starts to acquire data and display a
waveform. When a trigger is set up properly, it converts unstable displays into
meaningful waveforms.
When the oscilloscope starts to acquire a waveform, it collects enough data so that
it can display 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
display the waveform to the right of the trigger point.
DS1000CA series oscilloscopes provide five trigger modes: Edge, Pulse, Video,
Slope and Alternation.
