Object

column r/w Unsigned32

This attribute controls the number of probes the CMTS will use to
calculate the Rx MER per subcarrier. The average will be computed
using the 'leaky integrator' method, where reported Rx MER per
subcarrier value = alpha*accumulated values + (1-alpha)*current value.
Alpha is one minus the reciprocal of the number of averages. For
example, if N=25, then alpha = 0.96. A value of 1 indicates no
averaging. Re-writing the number of averages will restart the
averaging process.  If there are no accumulated values, the
accumulators are made equal to the first measured bin amplitudes.
              
This object cannot be changed while a capture is in progress. It will
return a value of 'inconsistentValue' if set while the value of
'docsPnmCmtsUsOfdmaRxMerMeasStatus' is set to a value of 'busy'.
