I would like to ask about a few SCXI boards.
1) The datasheet of the SCXI-1102 mentions a maximum sampling rate of 333 ksam/sec. However, no further details regarding sampling are given anywhere in the datasheet. I am confused. Does this board sample or not? If not, can I use any DAQ board to sample it?
2) The same question regarding SCXI--1126
3) The SCXI-1140 is called a "simultaneous sampling analog input." However, its datasheet does not mention sampling rates or resolution anywhere. What does this board do?

First of all, thanks for your prompt response. I would like to pursue this a little further.
1) Regarding the SCXI-1102 - the datasheet says 333 ksam/sec maximum sampling rate, but does not mention simultaneous sampling. Does this mean I cannot sample simultaneously from this board?
2) Let's say I have a chassis with one SCXI-1102 (thermocouples) sampling 12 channels and one SCXI-1520 (strain gauges) sampling 8 channels. I need to simultaneously sample the strain gauges at 100 ksam/sec, and simulatenously sample the themocouples at 100 sam/sec. If I understand your response correctly, I would need to add a DAQ board to the chassis that would do the actual sampling? What board could handle those sampling rates?
3) Do you have A-to-D board with over 16 input analog channels?
