The NI PXIe-1075 is an 18-slot PXI Express chassis engineered for high-speed test and measurement systems requiring extensive channel density and data streaming capability. It delivers up to 4 GB/s total system bandwidth with dedicated 1 GB/s per-slot performance across PXI Express modules, supported by a backplane compliant with PXI-5 and PXI specifications. The chassis accommodates one system timing slot, eight PXI Express peripheral slots, eight hybrid peripheral slots for mixed PXI/PXI Express module deployment, and one system controller slot with three expansion positions.
