Keysight (Agilent) M9023A PXIe High Performance System Module

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.

Technical Specifications

• Gen 3 PCIe specification


• Dual x8 cable links, each supporting up to 8 GB/s


• x16 combined mode delivers up to 16 GB/s aggregate bandwidth


• Supports 4x4 or x8/x16 backplane connectivity


• Standard x8 PCIe connectors for external cabling Cable Interface


• Samtec active optical x8 Gen 3 PCIe cables supported


• Maximum cable length: 100 meters


• Compatible with Keysight Y1202A and Y1203A PCIe cables Physical Characteristics


• Height: 3U


• Form factor: Single PXIe system slot module

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 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.
