Turning on Smoothing
Smoothing can be used to reduce noise that has relatively small peaks. By
turning on smoothing, the value of each point on a trace is represented by
the moving average over the values of several nearby points. The
smoothing aperture (percentage of sweep span) defines the range of
points to be included in the calculation of the moving average.
• You can define the smoothing trace by trace.
