The Keysight E1401A is a 13-slot C-size VXI mainframe engineered for high-density instrumentation in demanding automated test systems, data acquisition, and process control environments. This high-power chassis delivers substantial peak and dynamic current capability to support power-hungry VXI modules while maintaining signal integrity across all slots. The platform combines automatic VMEbus daisy-chaining, temperature-controlled cooling, and rear-panel serviceability to minimize system downtime and configuration complexity.
Technical Specifications
• Chassis: 13-slot C-size VXI mainframe
• Power Supply: Ultra-reliable design with over-temperature, over-voltage, over-current, and short-circuit protection. Auto-sensing input range: 100/120 VAC to 220/240 VAC; frequency: 48 Hz to 66 Hz
• Cooling System: Pressurized Air Channel technology with three temperature-controlled circulation fans. Independent airflow to each slot via pressurized plenum design; includes serviceable air filters
