Term interpretation
Sensitivity: Trigger circuit including sluggish in order to exclude the influences from signal noise and get the
stable trigger. The sluggish is adjustable among 0.2div~1.0div. It means when set on 1.0 div trigger circuit
don’t have any response to any signal of PK-PK range ≤1.0div which to exclude the influences from signal
noise.
