・If the conditions are met already when measurement is started (AND: all
trigger patterns are met, OR: one trigger pattern is met), triggering does not
occur at this slope. Triggering only occurs if the conditions are removed and
then met again.
・’AND’ cannot be set between the trigger sources using the RMS level trigger
and the logic trigger. When a shift is made from "OR" to "AND," the logic
trigger setting is turned OFF.

triggering occurs as shown in the figure below.
