6 Triggers

6.1.3. Trigger according to thresholds
Example: the trigger above is
Triggering if
Channel A1 increasing and equal to the threshold S1, value 0.000V OR
Channel A2 increasing and equal to the threshold S1, value 0.500V OR
Channel A2 increasing and equal to the threshold S2, value 0.500V OR
Channel A3 decreasing and equal to the threshold S1, value 0.500V
The same analysis is worth for the AND trigger (every thresholds).
