The Keysight E8460A is a high-density reed relay multiplexer module designed for switching applications within VXI mainframe systems. This C-size, 1-slot register-based VXI module integrates into Keysight VXI mainframes to provide multiplexing capability for automated test environments. The E8460A operates within mainframes offering VXIbus compliance, efficient air-cooled thermal management, and power supplies ranging from 175 W to 1690 W depending on mainframe selection. Integration with compatible mainframes such as the E8401A (500 W, 13-slot), E8403A/E8404A (1000 W, 13-slot), E8408A (175 W, 4-slot), E1401B (1690 W, 13-slot), or E8400A (700 W, 13-slot) enables flexible switching architectures for signal routing and multiplexing in instrumentation systems. The module benefits from mainframe features including rear-accessible power and cooling components for field maintenance, QUIC insertion/extraction systems, and integrated monitoring via front-panel indicators or remote VXIbus/RS-232 interfaces. Thermal management includes innovative air distribution systems with optional enhanced temperature, voltage, current, and fan monitoring throughout the chassis. The E8460A supports data acquisition, automated test systems, and field service applications requiring high-density relay switching within a compact VXI form factor.
