The National Instruments PXI-8156B is a PXI/cPCI embedded controller purpose-built for demanding test and measurement applications. It integrates essential PC peripherals directly onto the controller, preserving PXI chassis slots for instrument modules. The platform supports dual processor options—233 MHz Intel Pentium MMX or 333 MHz AMD-K6-2—with configurable memory up to 256 MB via two user-accessible SO-DIMM sockets.
