T1
T1: It is the time of trigger delay that can be set from 0 ~ 9999mS.
T2: It indicates the sampling of analog signal is done and the test goes the next DUT (/ACQ).
T3: It is the time of firmware calculation & judgment signal output completion (/EOT: T2 +
T3).
T4: It is the time of next trigger since the measurement ended. (The time length is depending
on the trigger signal.).
