Multiple Sample Rates

Hi,

I'm using DAQmx to acquire data in VB.NET (or C#) and I have successfully created a task to capture data on several channels across multiple modules plugged into a cDAQ chassis.

However, I have a requirement to capture different channels at different sample rates:

1. Is this possible across different channels on the same module?
2. Is this possible using different sample rates for different modules?
3. Or must I capture at a common highest sample rate and then decimate where necessary?

If this is possible, sample code to create such a task would be much appreciated.

TIA
