NI launches PXI Express expansion for multichassis data acquisition and RF systems
The simplified interconnectivity and industry-standard PXI-based architecture help increase system design efficiency and overall system performance in a variety of high-channel-count data acquisition and high-speed automated test applications including RF and semiconductor test.
The NI PXIe-8364/74 modules use x1 and x4 MXI-Express links, respectively, to connect downstream and upstream PXI Express chassis, and all PXI modules in the downstream chassis appear as local devices in the upstream chassis. Because MXI-Express links are software transparent, no interconnections require programming, which greatly simplifies multichassis system setup.
The modules use cabled PCI Express as their underlying communication technology for high bandwidth and low latency. The NI PXIe-8364/74 modules provide a maximum data bandwidth of 250Mbps and 1Gps. Engineers can use the new modules to create systems with multiple PXI Express chassis connected in complex topologies such as star, line or tree. Ideal combinations connect the new NI PXIe-8364/74 modules in upstream chassis with NI PXIe-8360/70 controllers in downstream chassis.
