Referring to this link http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/dbe7ac32661bcf9b86256ac000682154?OpenDocument

What's the difference between sample clock and sample per channel per second? Looks the same to me.

The sample clock is the clock that sets the timebase for channel operations on the board.  The samples per channel per second is the actual rate at which data can be transferred on a particular channel.

Hi Alex. So if i want to control the sample rate of my daq that would be 'samples per channel per second' correct'

[Alex A.]

Yes, that is the value which is your data acquisition rate.
