Explanation
This function is valid only on the 701250 (HS10M12) and 701255 (NONISO_10M12)
input modules.
At sample rates that allow box averaging, data is normally sampled at 10 MS/s and the
sampled data is decimated according to the record time and stored to the acquisition
memory. The internal sample rate is the same as the envelope mode.
When you use the box averaging function, moving average is computed on a given
number of data points (not simply decimating the sampled data), and the result is
sampled and stored to the acquisition memory.
