AI GND is an AI common signal that routes directly to the ground connection point on the devices. You can use this signal if you need a general analog ground connection point to the device. Refer to the When to Use Differential Connections with
How can I use the AI Sample Clock and AI Convert Clock signals on an M Series device to sample the AI channel(s)?
M Series devices use ai/SampleClock and ai/ConvertClock to perform interval sampling. As Figure
1/sample period = sample rate

Channel 1

ai/ConvertClock controls the convert period, which is determined by the following equation:
1/convert period = convert rate
This method allows multiple channels to be sampled relatively quickly in relationship to the overall sample rate, providing a nearly simultaneous effect with a fixed delay between channels.
