Hello Roxy,

I am assuming that you are using DAQmx to program your NI 9233.&nbsp; When you are using the DAQmx driver to program an acquisition on the 9233, there are several steps you go through.&nbsp; The simplest way to get started is to use the DAQ Assistant in LabVIEW. &nbsp;This <a href="http://zone.ni.com/devzone/cda/tut/p/id/2744" target="_blank">tutorial</a>&nbsp;shows how to configure this VI. &nbsp; One of the options for this VI is setting the sampling rate to use with the 9233.&nbsp; The <a href="http://digital.ni.com/manuals.nsf/websearch/7AD1EE99E57F31CC862573590050E4A6" target="_blank">9233 user manual</a>&nbsp;lists the valid sample rates you can use with your device. &nbsp;

I would also recommend reading through the links in my signature for more information on how to get started with DAQmx.&nbsp; The DAQ Assistant is great for getting started with an application, but you will eventually want to move to the lower level DAQmx VIs to get more control over you acquisition application.&nbsp; These resources provide great getting started information regarding this driver.&nbsp;

As Browning said, the DAQ Assistant is a way to get started quickly but at some point you will want to use the low level DAQmx functions. If you are already using them, fine. Did you check out the tutorials?
