What is the sequence of the samples being taken by AI mult PT?

[xwei]

I am using PCI 6034E board and SCXI 1100 module to do a multiple channel data acquisition. I have 5 channels so I set the scan rate at 1000scan/sec, and acquire 20 sample/channel in AI mult PT. So I guess that the computer will take 20 samples at each channel for all 5 channels. However, what is the sequence of these 100 samples being taken? Is it like:
Ch1, Ch2, Ch3 ... Ch5, and repeat this pattern for 20 times, or
is it : Ch1(20 times), Ch2(20 times), ... Ch5(20 time).
By the way, where can I find the information about this kind of questions? I am not a EE major. Thank you very much.

When you do a scan, it will sample Ch1, Ch2, Ch3, or in whatever order you specify and then it repeats. This is called multiplexing.

There's a lot of tutorials and white papers on NI's web site. One of them can be found here [broken link removed]. There is also a lot of shipping documentation with LabVIEW and NI-DAQ. If you select Help>Search the LabVIEW Bookshelf, one of the documents that covers DAQ is the LabVUEW Measurements Manual.
