3: No Overload Reject; 5: Special Spacer Mm; 6: Noise Bandwidth Ch.a Int; 7: Noise Bandwidth Ch.a Ioe - BRUEL & KJAER 2032 Instruction Manual

12.5.2. 2: Overlap
Overlap sets the averaging overlap in a number of samples from 1 to 2047. It can only
be used with a free running trigger. The default value is 0%, 50%, 75% or Maximum as
selected in the Averaging Overlap field of the MEASUREMENT SETUP.
12.5.3. 3: No Overload Reject
In normal operation, the 2032 automatically rejects data influenced by an input over-
load from an ongoing average. When No Overload Reject is set to 1, the reject is
overidden and averaging is performed irrespective of input overload.
12.5.4. 5: Special Spacer mm
Special Spacer mm is used to define the size in mm of the special microphone spacer
which can be selected in the Universal Parameter Sound Intensity Calibration fields,
see Section 12.3.1.
12.5.5. 6: Noise Bandwidth Ch.A INT,
7: Noise Bandwidth Ch.A IOE
If Special Parameter 6 is not equal to zero, then the normalised equivalent noise band-
width of the weighting function in Channel A is:
[ Special Parameter 6 ] . 1
o[
Special Parameter 7]
These parameters are used to define the noise bandwidth of the user-defined weight-
ing function, or to re-define the noise bandwidth of the other weighting functions from
their default values. These default values are:
Rectangular Weighting -
~
f
Hanning Weighting - 1 ,5 ~ f
Flat Top Weighting - 3,8 ~ f
Kaiser Bessel Weighting - 1 ,8 ~ f
12.5.6. 8: Noise Bandwidth Ch. B INT,
9: Noisewidth Ch.B IOE
As Special Parameters 6 and 7, but for the weighting function in Channel B. See Sec-
tion 12.5.5.
