Normal: This mode allows the Scopebox to acquire a
waveform only when it is triggered. If no trigger occurs,
the Scopebox keeps waiting, and the previous waveform,
if any, will remain on the display.
Single: In this mode, it only acquires the waveform that
generates for the first time the trigger conditions are met,
and then stops after finishing capture.
Source Select which channel as trigger signal.
Slope

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.
Normal: This mode allows the Scopebox to acquire a
waveform only when it is triggered. If no trigger occurs,
the Scopebox keeps waiting, and the previous waveform,
if any, will remain on the display.
Single: In this mode, it only acquires the waveform that
generates for the first time the trigger conditions are met,
and then stops after finishing capture.
