ATTENTION
Ne pas mettre la borne TRIGGER OUT en court-circuit et ne pas y appliquer une tension
externe. Si vous le faites, l’instrument risque de ne pas fonctionner correctement.
Trigger Output Terminal (TRIGGER OUT)
A 3.3 V CMOS level signal is output when the instrument triggers. The signal level is normally high
but goes low when a trigger occurs.
