The description of the figure above is as follows.
If CH1 = H, CH2 = L, CH3 = X, CH4 = X, Condition = True, Time = 350 ns: (The DL1620
is not equipped with channels 3 and 4.)
The trigger is activated at point B if Pulse < T.
The trigger is activated at points A and C if Pulse > T.
The trigger is activated at point C if T1 < PLS < T2 where Time1 = 350 ns, Time2 = 450
ns.
The trigger is activated at points A, B, and D if T1<PLS<T2 where Time1 = 350 ns,
Time2 = 450 ns.
The trigger is activated at point D if “Time out” is specified where Time = 450 ns.
