NI USB-6251 Sampling Rate Problem

[cf8989]

Hello,

I am using a piezo sensor with a NI USB-6251 to obtain voltage/time data. I am, however, only able to obtain a maximum of one reading every 0.02s.

I’ve tried using the same sensor and code with a BNC-2120/ PCI-6221 set-up and have been able to get a much better rate.

Does anyone have some advice on how to increase the rate with the NI USB-6251?

Thanks.
