Aaah, right, Nyquist rate and all that... So, I guess that means that, when you select a particular sample rate, there is an analog LPF of appropriate cutoff switched into the analog signal path, before it gets to the ADC. I hadn't realized that switching the digital sample rate probably also changed the analog hardware configuration.
