Object
column
hundredthDb Unsigned32
This attribute is the standard deviation of the dB values of the RxMER measurements of all active subcarriers. The standard deviation is computed directly on the dB values as follows: StdDev = sqrt(sum of (RxMER dB values - RxMER_mean)^2 / number of RxMER values)
