The Agilent/Keysight E1403C is a C-size VXI adapter module that enables integration of A- or B-size VXI modules into C-size VXI mainframes. It provides an active, fully buffered extension of the P1 connector, allowing modules that would otherwise be incompatible with C-size chassis to operate within the system architecture. The E1403C is engineered for slave-only operation and cannot be deployed in Slot 0 or with bus masters, ensuring proper system arbitration and backplane integrity.
Technical Specifications
• Module Type: C-size VXI adapter module
• Slot Width: 1-slot wide (standard); 2-slot wide optional (Option 010)
• Backplane Connection: Left-most slot only (applies to both configurations)
• Primary Interface: P1 connector with active, fully buffered extension
• Operational Mode: Slave-only; cannot function as bus master
• Power Rails: Connections to ±12V supplies available on breadboard area
• System Scalability: Supports unlimited adapter quantity per C-size mainframe
– Key Features
• Extends P1 connector signals with active buffering to maintain signal integrity
• Accommodates A-size and B-size VXI modules in C-size mainframes
• Breadboard area provides access to ±12V power supplies for custom buffer implementation
• Single backplane connection eliminates slot conflicts
• Slave-only architecture simplifies system arbitration in multi-adapter configurations
– Compatibility & Integration
The E1403C adapts A- and B-size VXI modules for C-size chassis operation. Many VMEbus cards meeting VXI mechanical and electrical constraints can be accommodated, though this configuration is unsupported. Multiple adapters can coexist within a single mainframe without addressing conflicts. Strict adherence to VXI specifications is required for reliable operation.
