The NI VXI-8340 MXI-3 Interface is a high-performance PCI-to-VXIbus bridge module that extends a computer’s control to remote VXI instrument systems. Using MXI-3 technology and National Instruments’ MITE and MXI-3 ASICs, this single-port interface enables a PC to function as an embedded controller within a VXI chassis, supporting direct instrument control and high-speed data acquisition in automated test environments. The module operates at 33 MHz PCI bus frequency and delivers peak throughput of 33 Mbytes/s, with sustained transfer rates up to 23 Mbytes/s across the MXIbus.
