Aggregate versus Single Channel Sample Rates

Simultaneous MIO X Series devices have one ADC per channel so the single channel maximum
sample rate can be achieved on each channel. The maximum single channel rate is the fastest
you can acquire data on the device from a single or multiple channels and still achieve accurate
results.
The total aggregate determines the maximum bus bandwidth used by the device. The total
aggregate sample rate is the product of the maximum sample rate for a single channel multiplied
by the number of AI channels that the device support.
Table 4-8 shows the single channels and total aggregate rates for Simultaneous MIO X Series
devices.
