National Instruments (NI) recently announced two DAQ modules and four PXI Express controllers. The PXIe-6259 and NI PXIe-6251 M Series are said to be the industry's first DAQ modules for PXI Express and promise fast analog and digital I/O with up to 250MBps dedicated per-slot bandwidth. The remote, embedded and rack-mount controllers, on the other hand, are touted to be the industry's highest-bandwidth controllers with up to 1GBps system and slot bandwidth.

The new PXI Express M Series DAQ modules feature up to 32 analog channels with 16bit, 1.25MSps sampling speed; up to four analog output channels with 16bit, 2.8MSps update rates; and 10MHz digital I/O on up to 32 lines. They feature the NI-STC 2 system controller, the NI-PGIA 2 amplifier and NI-MCal calibration technology for increased performance, accuracy and I/O, NI said. These devices are also suitable for high-channel-count data acquisition, high-speed control and manufacturing test applications.

With the NI PXIe-PCIe8371/2 x4 remote controllers, 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 1GBps total system bandwidth and are suitable 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, said to be the best in the industry, represents more than eight times improvement compared to other industry-standard cable interfaces such.

The new NI PXIe-8105 x4 dual-core embedded controller also offers up to 1GBps system bandwidth and 1GBps slot bandwidth and features a 2GHz 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 suitable for multitasking environments and multithreaded applications. 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 3.0 GHz 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 1 GB/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.
