To trigger the oscilloscope
The following exercise guides you through the trigger keys, knobs, and status
line.
1
Turn the trigger Level knob and notice the changes it makes to the
display.
As you turn the Level knob or press a trigger menu key, for a short time two
things happen on the display. First, the trigger level is displayed in inverse
video. If the trigger is dc coupled, it is displayed as a voltage. If the trigger is
ac coupled or if LF reject was selected, it is displayed as a percentage of the
trigger range. Second, if the trigger source is turned on, a line is displayed
showing the location of the trigger level (as long as ac coupling or low
frequency reject are not selected).

status line differently.
