- Ensure that the sample rate of the White Noise block matches the requirements of NI USB 4431 Analog Output.
- You may need to increase the sample rate to achieve a smoother, more continuous output.
- Verify that the White Noise block and the Analog Output block are synchronised in terms of their clock signals.
How to get continous white noise using Simulink to produce analog output from NI USB 4431 DAQ ?

I have to generate continuous white noise using the NI USB 4431 Analog output using SIMULINK. For that, I created an (i) white noise block and (ii) analog output block in the simulink, after this, I connected both blocks to generate the output.

When I am running the Simulink, the white noise generating through the NI DAQ is not continuous; it is staggering.

Hi Raja,
I understand from your query that you want to know why the generated white noise is staggering rather than continuous.
You can use the Band-Limited White Noise block to introduce white noise into continuous system. You can learn more about it from the given documentation:
You can try the following steps to ensure that the output you get is continuous:
Hope this helps.
