7.3. Triggering Control
There are two triggering modes including Edge triggering and Video triggering. Each trigger mode is set by different
function menu.
Edge triggering:
The edge trigger type triggers on the incoming signal edge. Use the edge trigger for all signals except for video related
ones.
Video triggering:
Perform video field trigger or line trigger on the standard video signals.
7.3.1. Edge Trigger
The Edge triggering is a mode by which trigger occurs at the triggering threshold value of the input signal edge. With the
Edge trigger selected, the trigger happens on the rise or fall edge of the input signal, shown as figure 34.
Figure 34: Edge trigger
The Edge trigger menu is described in the following table.
Triggering on the rise edge of the signal.
Triggering on the fall edge of the signal.
Acquisition of waveforms is possible even if there is no triggering
condition detected.
Acquisition of waveforms can only be done when the triggering
condition is satisfied.
The sampling is performed on a waveform when one trigger is
detected, then stop sampling.
With this mode selected, the DC component is prevented from
passing-though.
All components are allowed. (AC+DC)
