Averaging

Trace Averaging helps to smooth a trace to reduce the effects of random noise
on a measurement. The FieldFox computes each data point based on the
average of the same data point over several consecutive sweeps.
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. Average Count = 1 means
there is NO averaging.
