Trigger setting
Trigger indicates that when certain waveform meets the conditions that are
predefined according to the requirements, the Scopebox acquires the waveform
and its adjacent section, and then presents it on the screen.

Sweep
The sweep mode determines how the Scopebox behaves
in the absence of a trigger event. The Scopebox provides
three trigger modes: Auto, Normal, and Single.
Auto: It allows the Scopebox to acquire waveforms even
when it does not detect a trigger condition. If no trigger
condition occurs while the Scopebox is waiting for a
specific period, it will force itself to trigger.
When forcing invalid triggers, the Scopebox can not
synchronize the waveform, and then waveform seems to
roll across the display. If valid triggers occur, the display
becomes stable on the screen.
