9.5 Trace Configuration
A trace is a collection of measured data points. The trace settings determine how the
measured data is analyzed and displayed on the screen.

Mapping Samples to sweep Points with the Trace Detector
A trace displays the values measured at the sweep points. The number of samples
taken during a sweep can be much larger than the number of sweep points that are
displayed in the measurement trace.
