The NI PXI-8364 is an MXI-Express x1 daisy-chain module that extends PXI and PXI Express systems across multiple chassis interfaced to a single computer. This PXI Bus Extension Module enables high-bandwidth, software-transparent multi-chassis configurations supporting daisy-chain, tree, and star topologies—ideal for distributed test, measurement, and signal processing applications requiring synchronized operation across expanded hardware resources.
