Multifunction Data Acquisition for USB - USB-6221 and USB-6229 - National Instruments

National Instruments announced NI USB-6221 and USB-6229, multifunction data acquisition (DAQ) devices for USB. These new DAQ devices provide up to 32 analog inputs with a 250 kS/s per channel. With these new devices, NI has extended its USB DAQ offering to 40 devices, including low-cost devices starting at $99 USD, high-speed devices featuring 1 MS/s sampling speeds and modular USB data acquisition systems.

The USB-6221 and USB-6229 DAQ devices include up to 32 16-bit, 250 kS/s analog input channels; four 16-bit, 833 kS/s analog output channels; 48 digital I/O channels with up to 32 clocked at 1 MHz; and two 32-bit counter/timers.

The USB-6221 and USB-6229 feature NI signal streaming technology, which utilizes the bandwidth and performance of Hi-Speed USB technology to allow bidirectional high-speed transfer. The streaming technology makes it possible to acquire and generate multiple analog and digital I/O signals simultaneously. Designer can stream more synchronous analog and digital data for data-intensive applications than is possible using USB DAQ devices alone.With the plug-and-play USB, engineers and scientists have an easy-to-use, portable solution for their measurement, monitoring and control applications.

NI also offers software support for both programmers and non-programmers for development of this USB DAQ devices. The driver software features multi-device synchronization, automatic code generation and a high-level, open API that offers the same programming environment across devices and programming languages. NI-DAQmx can control every aspect of a data acquisition system. It works with NI LabVIEW, Measurement Studio, LabWindows CVI, C/C++, VB and .NET languages (C# and VB.NET).
