Reading AI from two devices at different frequency in C#

[Kumarppr]

Good day all,

I recently started working with NI DAQ cards, namely CDAQ and USB 6008, I am trying to read 3 channels AI from CDAQ at 10KHz and 1 AI channel from USB 6008 at 1KHz and then print to a csv file.

What i found in the examples was a multi-device synchronized continuous AI read. This example allows me to read the two devices at the same frequency. but I wanted to know if there is a way to read two devices at different frequency and display the data to DataTable in C#.

Any guidance will be highly appreciated.

Thank you.
