Agilent/Keysight E8400A

The Agilent/Keysight E8400A is a 13-slot C-size VXI mainframe that is the foundation for modular automated test systems. It delivers 700 W of usable power and implements a variable-speed cooling architecture that adjusts fan operation based on real-time internal temperature monitoring. The mainframe supports the full VXIbus specification and accommodates a range of C-size VXI plug-in modules, making it suitable for legacy test environments and new ATE deployments requiring VXI-based instrument integration.

Technical Specifications

• Form Factor: C-Size VXI mainframe, 13 slots


• Usable Power: 700 W with ample dynamic and peak current capability


• Cooling: Variable-speed fan with temperature-dependent modulation for efficient thermal management


• Backplane: Enhanced design for improved performance and reliability


• Weight: Approximately 150 lbs ship weight

Key Features

• VXIbus-compliant backplane with injector surface rails for module insertion and extraction


• Front panel diagnostic connector supporting local or remote system monitoring


• RS-232 connectivity option for continuous system oversight


• Rack-mountable configuration with optional rackmount kits


• Thermally optimized layout requiring unrestricted airflow for stable operation

Compatibility & Integration The E8400A houses C-size VXI plug-in modules and integrates with a selection of accessories including single-slot filler panels (E8400-44305, E8400-60202 for B/C-size slots) and airflow restrictors (E8400-80917). Cable trays and additional filler panels are available for system configuration. The mainframe works with integration into both existing legacy VXI systems and newly architected automated test platforms.
