When Trace Averaging is selected, then the Average Count setting is also
available. Average Count determines the number of sweeps to average. The
higher the average count, the greater the amount of noise reduction.
An average counter is shown in the left edge of the screen as Avg N. This shows
the number of previous sweeps that have been averaged together to form the
current trace. When the counter reaches the specified count, then a „running
average‟ of the last N sweeps is displayed.

Detection Method

In SA Mode, the X-axis is comprised of data points, also known as "buckets". The
number of data points is specified using the Resolution setting. Learn how on
page 78.
Regardless of how many data points are across the X-axis, each data point must
represent what has occurred over some frequency range and time interval.
From the frequency span of the measurement, the span of each data point is
calculated as (frequency span / (data points-1)). The detection method allows
you to choose how the measurements in each bucket are displayed.
