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 remote, embedded and rack-mount controllers are the industry's highest-bandwidth controllers with up to 1Gbyte/s system and slot bandwidth.
PXI Express offers the industry's highest bandwidth and highest-performance timing and synchronisation capabilities as well as software and hardware compatibility with the large installed base of existing PXI systems.
The new PXI Express M Series DAQ modules feature up to 32 analogue channels with 16bit, 1.25Msample/s sampling speed; up to four analogue output channels with 16bit, 2.8Msample/s update rates; and 10MHz digital I/O on up to 32 lines.

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.
As with other NI M Series DAQ devices, the new PXI Express modules feature the NI-STC 2 system controller, the NI-PGIA 2 amplifier and NI-MCal calibration technology for increased performance, accuracy and I/O.
They are ideal for high-channel-count data acquisition, high-speed control and manufacturing test applications.
With two new NI MXI-Express remote controllers, the NI PXIe-PCIe8371/2 x4 ("by four" - a link comprised of four PCI Express lanes), engineers can control PXI Express and CompactPCI Express systems from a PC equipped with PCI Express through a fully transparent, high-bandwidth cabled PCI Express link.
The x4 MXI-Express remote controllers provide 1Gbyte/s total system bandwidth and are ideal for high-frequency and high-resolution applications.
The NI PXIe-PCIe8371 features a cabled PCI Express link from a PC to one PXI Express chassis and the NI PXIe-PCIe8372 has two cabled PCI Express links to simultaneously control two PXI Express chassis for a higher channel count.
This bandwidth, the best in the industry, represents a more than eight times improvement compared with other industry-standard cable interfaces such as Hi-Speed USB, Gigabit Ethernet/LAN, GPIB (HS488), MXI-2 and MXI-3.
The new NI PXIe-8105 x4 dual-core embedded controller also offers up to 1Gbyte/s system bandwidth and 1Gbyte/s slot bandwidth and features a 2.0GHz Intel Core Duo processor T2500.
With two computing engines in one physical processor, a dual-core processor can simultaneously execute two tasks, which makes it ideal for multitasking environments, such as Windows XP, and multithreaded applications, such as the National Instruments LabView graphical development platform.
Engineers can use the NI PXIe-8105 controller for analysis-intensive applications such as communications test.
Finally, the NI PXIe-8351 x4 dual-core rack-mount controller is a 1U PXI Express controller that uses a cabled PCI Express connection to the PXI Express system.
The NI PXIe-8351 controller features a 3.0GHz dual-core Intel Pentium D processor 830, dual Gigabit Ethernet and SATA II RAID-0 hard drive configurations for applications requiring high-speed streaming to disk, such as acoustic imaging and RF spectral monitoring.
The rack-mount controller offers up to 1Gbyte/s system bandwidth.
The new PXI Express modules and controllers work with all existing PXI modules and software.
Engineers can use existing code written for the NI LabView graphical development platform, NI LabWindows/CVI ANSI C development environment and NI Measurement Studio for Microsoft Visual Studio with these new products. Request a free brochure from National Instruments ...
