Using Reference Tracking
The reference tracking functions allow you to track either the peak point
or a certain frequency of a measurement trace. It does this by adjusting
the reference level with each sweep so that the point of interest always
falls on the display reference line.
When reference tracking is on, marker values are displayed relative to
the point of interest. Limit lines are also displayed relative to the point of
interest when reference tracking is on. You may want to use relative
limits when the shape of a measurement trace is more important than
the absolute amplitude. See
“To Use Relative Limits” on page 4-36
example of using relative limit lines.
