National Instruments extend PXI Platform

National Instruments (NI) has announced two PXI Express products, the NI PXIe-6674T timing module and the NI PXIe-PCIe8388 controller.

“NI worked with the PXI Systems Alliance to introduce PXI in 1997,” said Eric Starkloff, NI vice president of product marketing. “The new timing module is the first in the market to provide access to the advanced PXI Express timing and synchronization features for best-in-class 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.”

The NI PXIe-6674T timing module 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. The first is a highly stable 10 MHz clock based on an onboard precision OCXO reference with a 50 ppb accuracy. The second is a clock up to 1 GHz with µHz resolution from the direct digital synthesis (DDS) clock generation circuit. It also features advanced trigger and timing routing with PXIe_DSTAR differential star trigger lines that offer less than 500 ps skews and 10 ns of delays.

The NI PXIe-PCIe8388 kit uses a x16 Gen 2 PCI Express link that provides up to 8 GB/s/direction of sustained throughput. Both new products work with NI software, such as the NI LabVIEW graphical development environment, as well as NI hardware, such as modular instruments.
