The Keysight M9018B is an 18-slot PXIe chassis engineered for high-performance modular test systems. It accommodates 16 PXIe hybrid slots, 1 system slot, and 1 timing slot, delivering PCIe Gen 2 fabric speeds with configurable bandwidth allocation across peripheral and system slots. The chassis supports peer-to-peer communication between any peripheral slots, eliminating system slot bottlenecks in demanding measurement applications.
