Averaging
Controls the number of sweeps to average. Sweeps are averaged successively as they are made available, so the
signal-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 —
Specifies the number of passes through the sweep data, the same smoothing filter is

Smoothing can be used in combination with data averaging. Smoothing may also be used on a
single sweep (“Continuous Sweep” can be enabled or disabled) or may be changed while sweeping.
