Explanation

Smoothing Function

This function attenuates the noise in the measured waveform. By using the Smoothing

function, areas on the waveform with a large amount of noise can be “smoothed out”

when measured. Note that when noise is superimposed on abrupt changes in the

spectrum, the peaks and valleys of the spectrum are integrated thereby reducing the

measurement resolution. Therefore, it is recommended not to use the Smoothing

function all the time, but rather to use it judiciously, checking the effects on the measured

spectrum. Also, if a relatively small number of samples is set relative to the measurement

span (or example, when UNCAL is displayed), the appropriate Smoothing function may

not be performed
