Keysight (Agilent) M9502A AXIe 2-Slot Chassis

The Keysight (Agilent) M9502A is a 2-slot AXIe chassworks with modular test and measurement systems requiring 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.
