Issue Details

The PXIe-6375 has 208 Analog input channels. According to the specifications sheet, the maximum sampling rate is 1MS/s.
What is the sampling rate, when more than one channel are used at the same time?


The PXIe-6375 is not a simultaneous sampling card, but it is multiplexed, and the multi-channel sampling rate is aggregate over the number of configured channels.
This means, with more than one channel configured, the highest rate that you could sample any individual channel at would be 1MS/s divided by the number of configured channels.
So if you have configured 10 channels, then the highest sampling rate per channel would be 1MS/s divided by 10. 

Additional Information

If only one channel is configured for PXIe-6375, then the maximum sampling rate which can be achieved is 3.846 MS/s.
