Sample Rate Considerations
E Series devices have a scanning architecture, which can impact the maximum sample rate in multichannel applications. To find the effective maximum sample rate for these devices, divide the device's sample rate by the number of channels in the task. For instance, if you create a task with 16 channels, and your device has a maximum sample rate of 1 MS/s, the maximum effective sample rate for that task is 62,500 kS/s (1 MS/16 = 62,500 kS).
