Can I output >10V using NI USB-6221 BNC?

[xinjian]

I need to output about 20V. The NI USB-6221 BNC I have has a limit of 10V. Is there a way to break that limit?

Is there another board to use instead?

Hello xinjian,

Thanks for your post!

If I could as you a little more about your application. Do you need a straight DC voltage at a paticular moment in time.  There is the NI-PXI 4110 that can do up to 20V. It also has the capability to cascade the outputs to get higher voltages than that. However this is only in the PXI form factor and not USB. There is no way to break the limit of the 6221 so the max AO will be 10V.

Let me know if this will work for you application and post back if you have any other questions!

Cheers!
