High-performance embedded controller, which features an Intel Core 2 Duo T9400 processor and is designed to significantly reduce test times for PXI Express - and CompactPCI Express-based automated test systems


  • Engineers can use this 3U embedded controller in any PXI Express chassis to create a compact, high-performance PC-based platform for many test, measurement and control applications
  • With its 2.53 GHz dual-core processor, 800 MHz DDR2 memory and 1 GBps total system bandwidth, the NI PXIe-8108 is ideal for advanced RF and wireless test applications, high-throughput data acquisition systems and other applications that require intensive analysis, signal or image processing
  • NI PXIe-8108 optimizes RF and wireless test applications because measurement speed is related to the computational performance of the test system's controller
  • The advanced operation of the NI PXIe-8108 controller helps engineers maximize their controller investments by delivering up to a 25 percent performance improvement over similar systems based on previous-generation NI embedded controllers
  • This results in significantly reduced RF and wireless test times including wireless local area network (WLAN) tests
  • For example, an NI WLAN Test System that incorporates the NI PXIe-8108 can deliver measurement times up to 10X faster than traditional WLAN instruments in WLAN protocol testing. Using the NI PXIe-8108, NI also has achieved similar test time reductions with other RF and wireless protocols including WiMAX, GPS, ZigBee, and RFID
  • I LabVIEW graphical system design software, a development environment that inherently supports multithreaded applications, can maximize the use of the Intel Core2 Duo T9400 processor's dual cores in the NI PXIe-8108 to separate tasks into individual threads and simultaneously execute those threads
  • This functionality helps engineers take advantage of the processor's computational ability to optimize processing load and reduce test times
  • Building on standard PXI industry specifications, a PXI Express system incorporating an NI PXIe-8108 embedded controller provides additional timing and synchronization features including a 100 MHz differential system clock, differential signaling and differential star triggers
  • By using differential clocking and synchronization, PXI Express systems benefit from increased noise immunity for instrumentation clocks and the ability to transmit at higher frequency rates
  • With these features, PXI embedded controllers from National Instruments deliver advanced performance, longevity, reliability and fast system recovery
  • Engineers already using PXI-based test systems easily can upgrade their embedded controllers to take advantage of the higher-performance NI PXIe-8108. Engineers using non-PXI systems can experience greater performance improvements by transitioning to a PXI solution based on the NI PXIe-8108 embedded controller
