The reason for this is that the maximum sampling rate of the board is for a single channel. By default, NI-DAQ configures your board for differential input. If you want to sample all of your channels, you have to divide the maximum sampling rate by the number of differential channels on your board. For example, an NI-6036E has a maximum sampling rate of 200,000 samples/second and 8 differential channels. In the NI-DAQ Test Panels you should be able to sample at approximately:
( 200,000 samples/second ) / ( 8 differential channels ) = 25,000 samples/second for 8 channels
