When in continuous sweep mode, the specified number of
averages is taken, then the averaging continues with each new

On Off
Initiates a digital averaging routine that averages the trace points
in an average duration resulting in trace “smoothing”. Increasing
the average duration will further smooth the trace.
The average is restarted when any of the following occurs:
• A new average duration is entered.
• Any related parameter (e.g., center frequency) is changed.
