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.
Address: 20 ( Q1
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.
