HOW TO USE THE INSTRUMENT 4 - 27
TRIGGER TRIGGER LEVEL
After each AUTOSET, the trigger level is always clamped within the
signal amplitude range to assure stable triggering on most signals. The
trigger level is adjustable, but it is limited between the minimum
(-100%) and the maximum (+100%) amplitude levels of the signal.
- Turn the TRIGGER LEVEL control.
As you turn the trigger level control, the
trigger level readout in the bottom of the
screen shows the trigger level relative
to the signal amplitude. For example, it
may appear as ’Level=+ 14%’.
