How do attain an actual scan rate of exactly 96kHz for AI capture?

[cadet003]

The actual scan rate and the scan rate for AI data Acq. seem to be different and due to the other software requirements involved in this project, I will need this to be exact.

Greetings,

To generate the requested 96 kHz scan clock, the DAQ device divides-down its 20 MHz timebase. Since 20M/96k does not result in an integer divisor, the closest scan rate you will be able to achieve is 96153.85 S/s (divisor of 208). Thus, if you need a scan rate of exactly 96 kS/s, you will need to provide an external scan clock.

Good luck with your application.
