Pattern Trigger (Enhanced Trigger) → Section 6.10
Multiple trigger sources are selected, and a trigger is activated when all of the trigger
conditions set for each trigger source become true or false. Trigger conditions are
established by setting combinations of the state (High or Low) of each trigger source.
Furthermore, one of the trigger sources can be used as the clock signal, and triggering is
synchronized with this clock signal.
