Determines the number of output word rate (OWR) samples to use in calculating low-rate results. Cycle Count
( N ) is an integer in the range of 10 to 8,388,607. Values less than 10 should not be used.

Wideband reactive power is calculated using vector subtraction. (See
on page 16). The value is signed, but has a range of 0 ≤ value < 1.0. The binary point is to the right of the MSB.
