Example:
o
Upper limit trigger range = 3.12 V and lower limit trigger range = -7.04 V, as illustrated
below. When adjusted beyond these two points, signal is no longer triggered and will
move across the screen.
o
(3.12V – (-7.04V) ) / 2 = 5.08 V. This will be the current trigger center level.
o
Turn the LEVEL knob until trigger level is set to 5.08 V level. Select “center” and
increase the value until the critical point where the signal turns from untriggered to
triggered (see image below):
