National Instruments has announced two new M Series multifunction data acquisition (DAQ) devices for USB. With the new NI USB-6221 and USB- 6229 DAQ devices, which provide up to 32 analog inputs with a 250 kS/s singlechannel sampling rate, NI has extendedits USB DAQ offering to 40 devices. The USB-6221 and USB-6229 – as well as bus-powered and other USB DAQ devices – feature NI signal streamingtechnology, which utilizes the bandwidth and performance of high speed USBtechnology to allow bidirectional high-speed transfer of data between the USBdevice and a computer.
NI signal streaming technology makes it possible to acquire and generate multiple analog and digital I/O signals simultaneously. Because the technology relies on message-based rather than register-based confi guration, much of the configuration takes place on the device, avoiding unnecessary USB transfers.
