button.
2. In the Measurements section, press the Att. button. Markers A and B
appear on the graph.
3. Place markers A and B at any two points on the trace. For more
information, see Using Markers on page 187.
4. Zoom in on the trace and fine-tune the marker positioning if necessary.
For more information, see Using Zoom Controls on page 137.
