A timer within the scope detects that the scope has not been triggered for a while and sets the sweep in motion. If it were set on the auto mode, the trace would default to freerunning if ever the trigger level were set above or below the waveforms amplitude.

This gives the user some control over how rapidly, or how often, the oscilloscope can be triggered. Ios,androidpartial function,win10,win8, win7, vista. The three trigger sweep modes are auto, normal, and single. On conventional desktop oscilloscopes, this is called trigger mode auto and. With the auto trigger mode, picoscope updates the display only when it detects a stable waveform. As st2000 points out, this isnt an artifact of the auto trigger mode as the oscilloscope believes its triggering properly. However with the software in digital scopes this can now be achieved. The trigger mode determines whether or not the oscilloscope draws a waveform if it does not detect a trigger. Changing the trigger moment in the multi channel oscilloscope software can be. When used in conjunction with triggered sweep aka, autotrigger disabled these modes will ensure that only the behavior youre looking for is acquired and.

If no trigger condition occurs while the oscilloscope waits for a specific period as determined by the timebase setting, it will force itself to trigger.
