TRIGger Commands
In order to make the waveform displayed more stable, it is necessary to set the
trigger system. The trigger determines when the oscilloscope starts to acquire data
and display a waveform. If 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.
The available trigger mode provided by DS1000E, DS1000D series digital
oscilloscopes are: Edge, Pulse, Video, Slope, Pattern, Duration and Alternation.
