NI USB-6008 12-Bit, 10 kS/s Low-Cost Multifunction DAQ With recent bandwidth improvements and new innovations from National Instruments, USB has evolved into a core bus of choice for measurement applications. The NI USB-6008 and USB-6009 are low-cost data acquisition (DAQ) devices with easy screw connectivity and a small form factor. With plug-and-play USB connectivity, these devices are simple enough for quick measurements but versatile enough for more complex measurement applications. Last Revised: 2010-04-07 • 8 analog inputs at 12 or 14 bits, up to 48 kS/s • 2 analog outputs at 12 bits, software-timed • 12 TTL/CMOS digital I/O lines • One 32-bit, 5 MHz counter • Digital triggering • Bus-powered • 1-year warranty
