The Keysight M9023A PXIe High Performance System Module is a 1-slot, 3U interface module that connects an external computer to a PXIe chassis via high-speed PCIe cable links. It enables external control of modular instrumentation, automated test systems, and data acquisition platforms without consuming instrument slots in multi-chassis configurations.

– Key Features
Flexible bandwidth configuration allows system architects to operate dual independent 8 GB/s channels or combine them into a single 16 GB/s link based on application throughput requirements. Multi-chassis daisy-chain operation in dual x8 mode eliminates the need for dedicated instrument slots when interconnecting multiple PXIe chassis.
The module integrates with Keysight host adapters—particularly the M9049A for optimized x16 operation and M9048B—and works with high-performance desktop or rack-mounted host computers. Extended cable length capability (up to 100 meters) accommodates distributed test environments and system architectures requiring physical separation between control hardware and instrumentation.
– Typical Applications
• External computer control of PXIe-based test platforms
• Multi-chassis instrumentation systems via daisy-chain configurations
• High-throughput data acquisition and signal processing
• Modular automated test equipment (ATE) with remote computer integration
– Compatibility & Integration
Designed for Keysight PXIe chassis including M9010A, M9019A, and M9046A models. Requires paired host adapter cards and Gen 3–rated PCIe cables for specification performance. Multi-chassis operation supports interconnection without occupying instrument measurement slots, preserving I/O capacity for test modules.
