Averaged Value

When the Averaged Value operator is selected, the math waveform
becomes the selected source waveform, averaged the selected number of
times.
The source waveform can be one of the analog input channels or one of
the previous math function waveforms.
Unlike acquisition averaging, the math averaging operator can be used to
average the data on a single analog input channel or math function.
If acquisition averaging is also used, the analog input channel data is
averaged and the math function averages it again. You can use both types
of averaging to get a certain number of averages on all waveforms and an
increased number of averages on a particular waveform.
As with acquisition averaging, averages are calculated using a "decaying
average" approximation, where:
Where N starts at 1 for the first acquisition and increments for each
following acquisition until it reaches the selected number of averages,
where it holds.
