On
, the linearity of low-level signals is improved. However, the ADC
dynamic range is reduced to make room for the dither. As a result, the noise floor of the
analyzer is somewhat compromised. So making measurements with ADC dither on gives
you better amplitude linearity, but turning ADC dither off gives you a lower noise floor
(better sensitivity).
