Trigger Level
Moving the joystick up or down will move
the Y position of the signal. Since the
trigger level is locked in the middle of the
display, moving the signal vertically has
the same effect as moving the trigger level
(fig. 47 to 49).
Modifying the trigger mode will switch off
the auto-range.
Trigger slope
Each move to the right of the joystick will
toggle the trigger. A symbol will appear on
the display (Fig. 50 & 51).
Triggering on the rising slope (Fig. 50):
the signal will only appear when a rising
slope is detected, i.e. the input voltage is
lower than the trigger level and exceeds the
trigger level.
