Averaging
Controls the number of sweeps to average. Sweeps are averaged successively as they are made available, so the sig-
nal-to-noise ratio improves over time. Up to 100 sweeps can be averaged. Sweep data averaging is only available
when the “Continuous Sweep” option is checked.

Smoothing
Enabling smoothing will filter out noise by averaging a specified number of neighboring points.

Smoothing Window Size - Determines how many points to average before and after a center point.
Smoothing Passes - Takes multiple passes thought the sweep data, applying the same smoothing filter on each pass.
Note: Smoothing can be used in combination with data averaging. In can also be used on a single sweep
(“Continuous Sweep” can be enabled or disabled) or even be changed while sweeping.
