National Instruments has announced two PXI Express products extending the platform’s performance and capabilities for multichassis systems - the NI PXIe-6674T timing and synchronization module and the NI PXIe-PCIe8388 8-GB/s/direction remote controller. Engineers can use these products to create high-performance PXI Express systems with tight synchronization and high system data throughput.

“The new timing module is the first in the market to provide access to the advanced PXI Express timing and synchronization features for clock and trigger routing for synchronizing PXI. The new remote controller interfaces PXI Express systems using the fastest cabled PCI Express link to double the throughput for high-speed data streaming applications,” said Eric Starkloff, vice president of product marketing, NI.

The NI PXIe-6674T timing module unlocks the most advanced timing and synchronization capabilities for PXI Express systems and generates and routes clocks and triggers between devices in a PXI Express chassis. It also can externally route signals to other PXI and PXI Express chassis or third-party instrumentation. The timing module can generate two types of clock signals - a highly stable 10 MHz clock based on an on-board precision OCXO reference with a 50 ppb accuracy and, a clock up to 1 GHz with µHz resolution from the direct digital synthesis (DDS) clock generation circuit.

The NI PXIe-PCIe8388 kit uses a x16 Gen 2 PCI Express link that provides up to 8-GB/s/direction of sustained throughput. Engineers can use the NI PXIe-PCIe8388 remote controller to control PXI Express systems from a x16 Gen 2 PCI Express slot in an NI rack-mount controller. For example, the remote controller

works with the new NI RMC-8354 (featuring Intel Core i7 processor) through a fully transparent, high-bandwidth cabled PCI Express link. With this level of data throughput performance, the remote controller is eight times faster than the company’s existing remote controllers. The remote controller also features a downstream port to create high-performance, multichassis systems by connecting to other PXI Express chassis as well as to other enclosures with general-purpose graphical processing units (GP-GPUs) for added computational ability.

Both new products work with NI software, such as the NI LabVIEW graphical development environment, as well as NI hardware, such as modular instruments.
