The Keysight E1482B is a C-size, 1-slot VXI-to-MXIbus interface module that bridges high-speed communication between VXI mainframes and external computers. Featuring the INTX PCB Assembly, this register-based VXIbus extender establishes transparent control and synchronization across multiple mainframe systems via the MXIbus interface. The module supports TTL triggering, transparent interrupts, and daisy-chain configuration, allowing distributed VXI architectures to operate as unified test systems.
Technical Specifications
• Module Type: VXIbus-to-MXIbus extender; register-based VXI module
• Form Factor: C-size, 1-slot configuration; typically installed in slot 0
• Primary Interface: MXIbus (E1489C) for external controller communication
• Secondary Interface: INTX PCB Assembly (removable)
• Signal Compliance: IC drivers and receivers meet VMEbus specification; MXIbus transceivers meet MXIbus specification
• Cable Options: 1-meter or 4-meter MXI and INTX cables (HP E1489-61604 compatible)
– Key Features
• Enables multiple VXIbus mainframes to function as a single system
• Transparent interrupt handling and TTL trigger distribution
• VXIplug&play-compatible interface
• Supports daisy-chain topologies across multiple mainframe systems
• INTX PCB Assembly removable for modular configuration
• Compatible with HP-UX controllers via E1489C ISA-MXI interface
– Typical Applications
• Multi-mainframe test systems with external workstation control
• Embedded and external controller-based VXI architectures
• Distributed trigger and timing distribution across multiple chassis
• Systems requiring extended connectivity beyond local VXIbus reach
– Compatibility & Integration
The E1482B integrates with EISA/ISA-to-MXIbus interfaces for HP-UX environments and supports MXIbus Econtroller cabling. Manufactured by National Instruments for HP/Agilent, the module maintains cross-compatibility across both instrument ecosystems. MXIbus daisy-chain support permits scaling to multiple-mainframe configurations without architectural redesign.
