National Instruments  has introduced 80-channel USB data acquisition devices, new BNC USB M series devices and a new USB-9237 C Series module.

The complete National Instruments USB data acquisition offering now spans more than 45 devices with single-channel sampling rates of up to 1.25 MS/s, analogue generation of up to 2.86 MHz and correlated digital I/O of more than 1 MHz for low-, mid- and high-channel-count applications.

The 80-channel USB M Series devices are high channel-count USB multifunction data acquisition devices, the BNC USB M Series devices provide direct BNC connectivity and the USB C series modules offer less expensive and more portable hardware.

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.

Using the 80-channel USB M series devices, engineers can collect more data with less equipment because the devices provide high-channel-count application solutions in a single device. The National Instruments USB-6225 and USB-6255 offer 80 channels for analogue inputs and up to 1.25 MS/s (750 kS/s aggregate) sampling rates per channel.

The USB-6225 and USB-6255 devices feature National Instruments signal streaming and provide up to 48 digital input/output lines and two counter/timers.

Engineers can choose either integrated connectivity or mass termination to connect to the devices. Mass termination provides access to National Instruments signal conditioning platforms or to custom boards.

National Instruments USB-6221, USB-6229, USB-6251 and USB-6259 BNC USB M Series devices include the standard M Series features along with direct BNC connectivity that provides up to 16 differential analogue inputs, four analogue outputs, eight digital I/O BNC connectors and up to 60 screw terminals.

The BNC USB M Series features BNC connectivity directly on the USB device, eliminating the need for an extra cabled accessory to house BNC connections.

BNC delivers easy and durable connectivity while achieving better noise rejection in a rugged, portable device ideal for benchtop, academic and field use.

National Instruments BNC devices have up to 1.25 MS/s (750 kS/s aggregate) sampling rates per channel, support National Instruments signal streaming technology, provide up to 48 digital I/O lines and feature two counter/timers.

National Instruments M Series technologies including the National Instruments -STC 2 system controller, National Instruments -PGIA 2 amplifier and National Instruments -MCal calibration, provide more performance, more accuracy and more I/O than other data acquisition devices.

The new USB M Series devices combine M Series performance with Hi-Speed USB ease of use to handle a wide range of applications including automated test, process control and sensor measurements. All M Series devices support National Instruments signal streaming technology, making it possible to acquire and generate multiple analogue and digital I/O signals simultaneously.

The USB-9237, based on the National Instruments C Series platform, offers high-speed performance in a compact form factor for low-channel-count applications including strain, load, pressure, and other bridge-based measurements.

The bus-powered module removes the need for an external power supply and offers NATIONAL INSTRUMENTSST-traceable calibration; 24-bit resolution; direct connectivity; 50 kS/s simultaneously sampled analog inputs; quarter-, half- and full-bridge completion; up to 10 V internal excitation; and transducer electronics data sheet (TEDS) smart sensor compatibility.

Engineers can easily acquire data from these National Instruments USB devices with the included National Instruments-DAQmx driver software and National Instruments LabVIEW SignalExpress LE, an interactive measurement software for quickly acquiring, analyzing and presenting data.

National Instruments-DAQmx software offers time-saving features such as code generation; more than 3,000 measurement examples; device simulation; connection diagrams; and compatibility with LabVIEW, ANSI C/C++, C#, Visual Basic .NET and Visual Basic 6.0.

Engineers can use all of these devices with National Instruments software, including LabVIEW, LabVIEW SignalExpress, Measurement Studio and LabWindows /CVI and hardware such as PXI modules from National Instruments.
