Edge On A Trigger (Enhanced)
While state condition A is met, the DL850/DL850V triggers on the OR of multiple trigger source
edges.

Condition A is being met
OR Trigger
The DL850/DL850V triggers on the OR of multiple trigger source edges.
AND Trigger
The DL850/DL850V triggers on the AND of multiple trigger source conditions. The DL850/DL850V
triggers when all the specified conditions are met at a single point.
Period Trigger
The DL850/DL850V triggers on a specified period of occurrence of state condition B. The DL850/
DL850V triggers when state condition B occurs again.

Pulse Width Trigger
The DL850/DL850V triggers according to the relationship between the state condition B
achievement time and the specified reference times (Time or T1 and T2).

Wave Window Trigger
The DL850/DL850V creates real-time templates (Wave Window) using a number of cycles directly
preceding the current waveforms. The DL850/DL850V compares the current waveforms to the real-
time templates and triggers if one of the current waveforms falls outside of its real-time template.
