Windowing is a signal conditioning process that reduces the error in average measurements made in
the presence of periodic signals and noise. Two window functions are available: Rectangular and
Hanning. At power-on, the measurement window is Rectangular.
The Rectangular window calculates average measurements without any signal conditioning.
However, in the presence of periodic signals such AC line ripple, a Rectangular window can introduce
errors when calculating average measurements. This can occur when a non-integral number of cycles
of data has been acquired due to the last partial cycle of acquired data.
One way of dealing with AC line ripple is to use a Hanning window. The Hanning window applies a cos4
weighting function to the data when calculating average measurements. This attenuates the AC noise
in the measurement window. The best attenuation is achieved when at least three or more waveform
cycles are in the measurement.
