Hz Unsigned32
This attribute controls the frequency span of each
segment (instance) in the docsIf3CmSpectrumAnalysisMeasTable.
If set to a value of 0, then a default span will be
chosen based on the hardware capabilities of the
device. Segments are contiguous from the
FirstSegementCenterFrequency to the
LastSegmentCenterFrequency and the center frequency
for each successive segment is incremented by the
SegmentFequencySpan.
The number of segments is (LastSegmentCenterFrequency -
FirstSegmentCenterFrequency)/SegmentFrequencySpan + 1.
A segment is equivalent to an instance in the
docsIf3CmSpectrumAnalysisMeasTable. The chosen
SegmentFrequencySpan affects the number of entries in
the docsIf3CmSpectrumAnalysisMeasTable. A more granular
SegmentFrequencySpan may adversely affect the amount of
time needed to query the table entries in addition to
possibly increasing the acquisition time.
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 object to the closest valid value.
