Let's view the stored data on a chart graph.

To view R on the chart, you need to display Trace
3. The chart now displays R vs time (frequency).

Auto Scale the graph.

To manually adjust the graph scale, you change

seeks the max or min within the region. Cursors
on split screen charts can also be linked together.

Set the cursor display to show the frequency and
trace value of each data point. The reference fre-
