Object
This attribute controls the center frequency of the
first segment for the spectrum analysis measurement.
The frequency bins for this segment lie symmetrically
to the left and right of this center frequency.
If the number of bins in a segment is odd, the segment
center frequency lies directly on the center bin.
If the number of bins in a segment is even, the segment
center frequency lies halfway between two bins.
Changing the value of this attribute may result in
changes to the docsIf3CmSpectrumAnalysisMeasTable.
Note that if this attribute is set to an invalid value,
the device may return an error, or may adjust the
value of the attribute to the closest valid value.
