While state condition A is met, the DL850E/DL850EV triggers on the OR of multiple trigger source
edges.

Condition A is being met
OR Trigger
The DL850E/DL850EV triggers on the OR of multiple trigger source edges.
AND Trigger
The DL850E/DL850EV triggers on the AND of multiple trigger source conditions. The DL850E/
DL850EV triggers when all the specified conditions are met at a single point.
Period Trigger
The DL850E/DL850EV triggers on a specified period of occurrence of state condition B. The
DL850E/DL850EV triggers when state condition B occurs again.

Wave Window Trigger
The DL850E/DL850EV creates real-time templates (Wave Window) using a number of cycles
directly preceding the current waveforms. The DL850E/DL850EV compares the current waveforms
to the real-time templates and triggers if one of the current waveforms falls outside of its real-time
template.
