The primary NCH publication contains some information on sampling rates: https://pubmed.ncbi.nlm.nih.gov/35853958/

The total length of recording in the NCH Sleep DataBank amounts to 40,884 hours, where the minimum length of study is 3minutes, the maximum is 16.5hours, and the mean is 10.3hours. 94.85% of the fles contain between 8 and 12 hours of recordings, and the patients slept for a subset of those times. Users of the dataset should take into account that the majority of the recordings (3,204) are collected with a sampling frequency of 256Hz, but 581 studies were sampled in 400Hz, and the rest (199) in 512Hz.

Thanks for checking out the site.
