Edge Triggering
The edge trigger is one of the most common trigger modes and is activated when
voltage rises above or falls below a preset threshold. This trigger type allows you to
configure the trigger mode, threshold, trigger channel and pulse direction settings.
Tap Done to save the settings or tap Cancel to exit without saving.
NOTE
The oscilloscope switches to the continuous mode if the time base is set to more
than or equal to 200ms/div. The Edge Triggering is supported in the continuous
mode.
Trigger Mode
Four trigger modes are available: None, Auto, Repeat and Single.

Trigger Mode
Description
None
In this trigger mode, the oscilloscope can continuously capture
data, without waiting for a trigger event.
Auto
In this trigger mode, the oscilloscope will wait for a trigger
before capturing data. It can automatically update after a short
period, even if the signal does not across the trigger point.
