Note When changing from 12 MHz to 6 MHz mode, the DSP on which the parameter is defined may no
longer be valid. If so, redefine the histogram on a DSP where the parameter is meaningful.

The radio attribute whose data is to be collected as a histogram.
in (Interference + Noise) The interference plus noise power levels are computed
by the hardware on a burst-by-burst basis.
inr (Interference + Noise Ratio) The ratio of the interference plus noise power
levels captured by the first antenna to the second antenna on a burst-by-burst
basis. This value is specified as a log to base 2 number.
Note This parameter is available for a dual antenna system only.
constVariance (Constellation Variance) The average energy of the constellation error
signal—the error between the received (noisy) constellation symbol and the
nearest ideal constellation symbol. Constellation Variance is a measure of the
Signal to Interference plus Noise ratio (SINR) for that tone. On a single antenna
system, it is proportional to (SINR)
-1
. On a dual antenna system, it represents a
composite value that is proportional to (SINR)
-1
.
