2.1.6.2 On
When
ADC Dither is 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).

2.1.6.3 Off
When
ADC Dither is Off, the instrument noise floor is improved. If ADC dither is on 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 improved amplitude linearity. but turning ADC dither off gives you a lower noise floor
(better sensitivity).
