hundredthsbin Unsigned32
This attribute allows the user to request an equivalent
noise bandwidth for the resolution bandwidth filter used
in the spectrum analysis. This corresponds to the
spectral width of the window function used when performing
a discrete Fourier transform for the analysis.
The window function which corresponds to a value written
to this object may be obtained by reading the value of the
WindowFunction attribute.
If an unsupported value is requested, the device may
return an error, or choose the closest valid value to the
one which is requested.
If the closest value is chosen, then a subsequent read of
this attribute will return the actual value which is in use.
