The Keysight M9022A PXIe System Module is a 3U single-slot module that serves as the system interface between a host PC and a PXIe chassis. It delivers high-bandwidth connectivity via Gen 3 PCIe, enabling scalable modular instrumentation architectures without the need for embedded controllers in single-chassis configurations.
Technical Specifications
PCIe Architecture
• Gen 3 x8 link with up to 8 GB/s data bandwidth
• Standard x8 PCIe connector for cable-based connections
• Supports 4×4 or x8/x16 backplane connectivity options
• Cable reach extends to 100 meters using Samtec active optical x8 Gen 3 PCIe cables
Power Supply
• Draws 3.3 V and 12 V from chassis backplane connector
• Chassis-dependent voltage gating may require manual switch configuration
– Key Features
• Single-slot, 3U form factor for integration into PXIe chassis system slot
• Backward compatible with Gen 2 chassis; delivers Gen 2 link speeds to legacy systems
• Multi-chassis capability: supports up to 6 PXIe or AXIe chassis via star or cascade topologies when paired with M9037A embedded controller
• Cascade configurations at x8 link width enable six-chassis strings without external compute
– Typical Applications
• Remote instrumentation systems with extended PC-to-chassis separation
• Multi-chassis test platforms requiring external host integration
• High-data-rate measurement applications exploiting Gen 3 PCIe throughput
• Distributed ATE architectures spanning multiple modular chassis
– Compatibility & Integration
Optimal performance is achieved with the M9048B Gen 3 x8 Host PC adapter card and Keysight Y1202A or Y1203A PCIe cables verified at Gen 3 speeds. The M9022A integrates with M9021A, M9023A, and M9024A system modules in multi-chassis configurations. Keysight’s Multi-Chassis Designer tool facilitates system planning across multiple chassis installations.
