More options in USB-based data
acquisition
With the addition of the NI USB-6221 and USB-6229, NI has extended its USB DAQ offering to 40 devices.
National Instruments has announced two new high-performance 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 analogue inputs with a 250Ksample/s single-channel sampling rate, NI has extended its USB DAQ offering to 40 devices

Modules condition a range of sensor signals
National Instruments has released new Signal Conditioning Component modules for frequency to voltage conversion, integrated circuit piezoelectric accelerometers and RTDs.
The complete NI USB offering now includes low-cost devices starting at GBP 65, or Eur 95, high-speed devices featuring 1Msample/s sampling speeds and modular USB data acquisition systems for low-, mid- and high-channel-count applications.
The USB-6221 and USB-6229 - as well as bus-powered and other high-performance USB DAQ devices - feature NI signal streaming technology, which uses the bandwidth and performance of High-Speed USB technology to allow bidirectional high-speed transfer of data between the USB device and a computer.
NI signal streaming technology makes it possible to acquire and generate multiple analogue and digital I/O signals simultaneously.

More measurement options from real-time software
The newest version of LabVIEW Real-Time offers more measurement options and improves development time with superior performance and easy-to-use networking functions.
Because the technology relies on message-based rather than register-based configuration, much of the configuration takes place on the device, avoiding unnecessary USB transfers.
Engineers can stream more synchronous analogue and digital data for data-intensive applications than is possible using USB DAQ devices alone.
Additionally, with the plug-and-play connectivity of USB, engineers and scientists have an easy-to-use, portable solution for their measurement, monitoring and control applications.
The USB-6221 and USB-6229 DAQ devices offer many features equivalent to their PCI M Series counterparts.
The new devices include up to 32 16bit, 250Ksample/s analogue input channels; four 16bit, 833Ksample/s analogue output channels; 48 digital I/O channels with up to 32 clocked at 1MHz; and two 32bit counter/timers, all backed by M Series technology including a low-noise NI-PGIA 2 amplifier and NI-MCal, a third-order calibration methodology correcting for gain, offset and nonlinearity errors at all input ranges.
Additionally, National Instruments USB DAQ devices have software support for both programmers and nonprogrammers.
Each device is shipped with free data-logging software to help users take full advantage of the ease of use and plug-and-play capabilities offered by USB by shortening time to measurement.
For programmers, NI-DAQmx driver software and measurement services - a powerful suite of data-logging tools, configuration management and wizard-like development interfaces - can dramatically decrease the hidden costs of software development, system setup, configuration and calibration time.
The driver software features multidevice synchronisation, 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, from configuration to application development.
The software driver works with National Instruments LabView, LabWindows/CVI, Measurement Studio and SignalExpress, as well as C/C++/C# and Microsoft Visual Basic and Visual Studio.NET languages. Request a free brochure from National Instruments ...
