Explanation
This function is valid only on the 701250 (HS10M12) and the 701255 (NONISO_10M12).
At sample rates that allow box averaging, data is normally sampled at 10 MS/s and the
sampled data is decimated according to the T/div setting and stored to the acquisition
memory. The internal sample rate is the same as the envelope mode.
For details, see appendix 1, “Relationship between the Time Axis Setting, Sample Rate
and Record Length.”
When you use the box averaging function, the operation is different. Moving average is
computed on a given number of data points and the result is sampled and stored to the
acquisition memory.
