    Chapter5 Operation Methods S/N ratio measurement with average With S/N ratio measurement with average, the noise floor is lowered with averaging. The noise power is obtained with automatic interpolation from this noise floor lowered with averaging, so the S/N ratio can be improved. Generally with a modulated laser beam, the noise floor rises, so by using averaging, the noise floor can be lowered to the real noise level and the accurate S/N ratio can be measured.
