7.5 Triggering Control
There are two triggering modes including Edge triggering and Video triggering. Each trigger
mode is set by different function menu.
Edge triggering:
It occurs when the trigger input passes through a given level along the specified
direction.
Video triggering:
Perform video field trigger or line trigger on the standard video signals.
The following describes the Edge triggering and Video triggering menus respectively.
7.5.1 Edge Triggering
The Edge triggering is a mode by which trigger occurs at the triggering threshold value of the
input signal edge. With the
Edge triggering
selected, the trigger happens on the rise or fall edge
of the input signal, shown as the following figure.
The
Edge triggering
menu is described in the following table.
