The Keysight (Agilent) M9502A is a 2-slot AXIe chassis designed for modular test and measurement systems requiring high-performance interconnect and compact form factor. This 2U instrument integrates an Embedded System Module (ESM) that manages chassis operations and provides external controller connectivity via Gen 2 x8 PCIe and Gigabit LAN. Each of the two instrument slots delivers 200 W cooling capacity and supports Gen 2 PCIe x4 links with maximum data rates of 2 GB/s per slot. The ESM distributes a secondary PCIe data fabric alongside a 62-pair local bus for adjacent module signaling.
