The Keysight M9021A PCIe Cable Interface is a 3U, single-slot module that establishes extended-distance PCIe connectivity between a Keysight M9018A PXIe Chassis and an external host computer. It provides transparent access to all PXI and PXIe modules within the chassis, enabling remote instrument control and high-speed data transfer via cabled PCIe links up to 2 meters in length.
Technical Specifications
• PCIe Architecture: Gen 2, x8 lane configuration
• Per-Lane Data Rate: 5 GT/s
• Maximum Data Bandwidth: 4 GB/s (external computer to PXIe backplane); 2 GB/s (between chassis)
• Power Consumption: 5 W (typical)
• Power Supply: 3.3V and 12V from M9018A chassis backplane top connector
• Operating Temperature Range: 0 to 55 °C
• Form Factor: 3U PXI, occupies one slot
– Key Features
• Front panel x8 PCIe iPass connector for host connection
• Direct x8 link to PXIe backplane
• Compatible with x8 cabled PCIe connectors and passive cables up to 2 meters
• Switchable configuration: Target mode (slot 1) or Host mode (hybrid slots 2, 6, 11, 15) via S301 DIP switch selection
• Typical power draw of 5 W minimizes thermal load on chassis
– Interfaces & Cabling
• Single x8 PCIe iPass front panel connector
• External connection via standard x8 cabled PCIe cable
• Keysight Y1202A (2 meter, x8) and 0.5 meter x8 PCIe cables available as accessories
– Compatibility & Integration
• Designed exclusively for the M9018A PXIe Chassis; not compatible with standard PXIe system slots in other platforms
• Pairs with Keysight M9048A Gen 2 x8 Host PC card for optimal performance
• Supports Windows 7 and Windows 10 (32-bit and 64-bit editions)
• Compatible with IVI-COM, LabVIEW, and IVI-C compliant drivers
• Required power sequencing: power on chassis before host PC; power down host PC before chassis
