How can i know if DAQ hw support "buffered task" and "Sample Timing Hw"?

[ringos75]

Hi,
i'm choosing the corrent DAQ hw for my application. I read in the NI-DAQmx documenation that if would use the DAQmxRegisterEveryNSamplesEvent(..) function, the hw should support the "bufferd tasks". How Can i know what DAQ device support this feature? Then, I know not all the DAQ device support the "Sample timing hardware". How can i know what DAQ hw use this timing type? Does the NI PCI-6220/6221 support these features?

Thanks in advace.

PS: sorry .. but i'm new of "NI World".

All of the Multifunction I/O (MIO) products, including the PCI-622x products, support hardware timing and buffered analog input tasks.

In general, if a product's specifications include the analog input sample rate (e.g. "up to 200KS/s") then that means the product supports hardware timing and buffered analog input.
