Type of averaging

Num. Aver-
ages
1 to 255
Number of averages.
Overlap
0 % to 99 %
Overlap when editing
or calculating the FFT.
It is expedient to incre-
ase the overlap at
lower frequencies, but
as the overlap increa-
ses the similarity of the
information contained
in the calculated FFT
averages also increa-
ses. As a guide value
an overlap of 50 % is
advantageous below 2
kHz.
