The NI 8352 and NI 8353 rack-mount controllers can be bundled with the appropriate MXI-Express or MXI-4 remote controllers for remote control of PXI or PXI Express chassis. The controllers offer high computing performance and make it easy to achieve high sustainable I/O bandwidth of up to 832 MB/s when bundled with a MXI-Express kit. With standard redundant array of independent disk （RAID） - configured hard drives for Windows-based systems, these controllers are ideal for high-end test and measurement applications. The new NI 8352 and NI 8353 rack-mount controllers are based on the Intel dual-core Core 2 Duo and quad-core Core 2 Quad processors, respectively. These multicore processors are designed to simultaneously execute multiple computing tasks on separate CPU cores. Using the multithreaded nature of NI LabVIEW software, test engineers can scale applications based on the total available number of cores and can benefit from faster, more flexible applications.
