Maximum cDAQ trouhgput

[smi38]

Hi there,

If I have cDAQ 9179, full with 14 NI 9220 C Series Analog Input Module, would it be possible to acquire continuously the full 448 channels (32*14) at a sample rate of 100kS/s ?

If no, what are the limitations ?

Thx,

     Hello Sébastien,

Have you seen that document?

What Is the Maximum Throughput On My cDAQ Device?

Does it answer your question?

Thanks

I think the last sentence in that linked pages is in error:

Because the total rate of data transfer during this application (8.6 MB/s) does not exceed the maximum throughput of the 9179's USB 3.0 bus (250 MB/s), there should be bandwidth issues acquiring data at these rates on this device. 

It is missing 'not':

Because the total rate of data transfer during this application (8.6 MB/s) does not exceed the maximum throughput of the 9179's USB 3.0 bus (250 MB/s), there should NOT be bandwidth issues acquiring data at these rates on this device.
