GAINU can be adjusted in a range from -2.17 x nominal to
2.16 x nominal
GAINU=0 (output subcarrier contribution of U = 0)
GAINU=0x76 (output subcarrier contribution of U = nominal)
White to black = 100 IRE
GAINU can be adjusted in a range from -2.05 x nominal to
2.04 x nominal
GAINU=0 (output subcarrier contribution of U = 0)
GAINU=0x7D (output subcarrier contribution of U = nominal)
