  6. Digital CDS Experience High sampling rates let you see subtle features(How fast is the CCD output settling? Is it ringing?) For higher frequencies (1 MHz), every extra sample averaged lowers noise, close to theory For lower frequencies (100 kHz), balance with 1/f noise – samples prefer to be close to SW transition Higher analog bandwidth gives faster settling, easier to avoid subtle non-linearities ADC power falls with sample rate – use lower frequencies in production after tuning
