The USB-6008/6009 devices provide eight single-ended analog input (AI) channels, two analog output (AO) channels, 12 DIO channels, and a 32-bit counter with a full-speed USB interface.

For specifications, refer to the USB-6008 Specifications and the USB-6009 Specifications available at ni.com/docs.

The following table compares the USB-6008 and USB-6009.
