Uses of NI 6585B external clock

[mahendra21]

Hi all, I want to sample the digital data using global clock (external clock) instead of the internal clock in the 6585b data module with the 7965R card. I am using the global clock in SCTL loop for sampling. Please give me the detail whether the sampling happens as per the clock provided to global clock externally with variable frequency range in runtime or it is fixed.
