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 Points setting. Learn more in
"Points " on page
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.
