Sample Rate

What is the default sample rate of an NI board?   

 

I can not find anything in DAQmx that lets you set this.  I recall that the sample rate across all the inputs is 256k samples/second.

There are hundreds of "NI boards" - what exact model are you referring to?

You can get the supported sample rates from the device specifications

The sampling rate applies only to hardware time sampling, in other words, if you used DAQmxTiming API on your Task.

 

If you never configured DAQmxTiming, it means your task is software timed, in this situation, there is no sampling rate concept as the hardware will generate/acquire data whenever the software tells it to and how often it does this depends on how often the software tells the hardware to.

 

So, there is no concept of a "default" sampling rate, though the DAQmxTiming API typically uses 1000Hz as a default value for the sampling rate parameter.
