Samples per channel on sample clock VI "specifies the number of samples to acquire or generate for each channel in the task if sample mode is Finite Samples.
If sample mode is Continuous Samples, NI-DAQmx uses this value to determine the buffer size"
So, in continous mode, this parameter does not specify 'number of samples to read' per iteration during DAQmx Read. Now, samples to read on DAQmx read Function does this job.
Hope this answers your query
