RIGOL Chapter 5 To Trigger the Oscilloscope
5-52 MSO7000/DS7000 User Guide
During the adjustment of trigger level, two trigger level lines appear on the screen,
and they move up and down with the change of the trigger level. At the same time,
the real-time trigger level and slope information is displayed at the lower-left corner
of the screen (as shown in the figure below, H indicates the upper limit of the trigger
level, L indicates the lower limit of the trigger level, and △ indicates the trigger level
deviation). When you stopping modifying the trigger level, the trigger level line and
the trigger level information at the lower-left corner of the screen disappear in about
2 s. The current trigger level deviation is displayed at the upper-right corner of the
screen.
