Use the vertical menu to perform these tasks.
Press the main-menu button Coupling. Use the side menu to select DC, AC, or
ground (GND) coupling.
Press the main-menu button Invert. Use the side menu to turn invert off and on.
When you turn invert on, the selected waveform “flips” (reverses polarity)
around the zero volt axis. Figure 3–3 shows an inverted pulse signal.
NOTE. Invert flips the waveform, but it does not alter the trigger level accord-
ingly. To obtain a stable trigger after inverting a waveform, press SET LEVEL
TO 50%.
