PXIe-PCIe8375 MXI-Express remote controller

National Instruments launches a remote controller for PXI Express-based ATE, measurement and control systems. The high-bandwidth fibre-optic NI PXIe-PCIe8375 MXI-Express remote controller for PXI Express integrates an x4 PCIe link for a low-latency interface with sustained bandwidth of up to 838MBps to and from an NI rack-mount, Dell or Hewlett-Packard host PC for a variety of applications.

Offering increased distance between the host PC and chassis, the fibre-optic cable and controller interface of the new controller, enables improved electrical isolation and greater cabling flexibility compared to a copper remote controller cable and interface. The controller delivers high-bandwidth performance at distances of up to 100m compared to the 7m distance afforded by using a passive copper cable and remote controller interface.

The NI PXIe-PCIe8375 remote controller is suited for distributed test, measurement and control systems that require high-bandwidth, low-latency data transfers to and from the host PC and PXI Express instrumentation. These include high-channel-count DAQ systems used for harsh environmental testing and control I/O or measurements in particle accelerators and large test and research facilities. Other use cases include applications such as signal intelligence and mixed-signal testing, which require high-data bandwidth for streaming high-frequency measurements back to the host PC with minimal electrical noise in the system. The 10-, 30- and 100m fibre-optic cable lengths of the NI PXIe-PCIe8375 provide a variety of options for designs that require additional electrical isolation in their systems, including protection against electrical shorts and differing ground potentials between the host PC and distributed instrumentation systems.

The NI PXIe-PCIe8375 remote controller's PCIe configuration also ensures software transparency and compatibility with no additional programming when upgrading PCI- and PXI-based MXI-3 and MXI-4 systems. The software transparency and compatibility apply to software applications and drivers as well as industry-standard desktop computers, servers and workstations. The new fibre-optic PXI Express remote controller also works seamlessly with NI software including the LabVIEW graphical system design environment, NI TestStand test management software, the LabWindows/CVI ANSI C development system, SignalExpress interactive measurement software and new NI VeriStand real-time test configuration software.
