Keysight / Agilent / HP E1403C VXI A/B to C-Size Adapter

The Keysight/Agilent/HP E1403C is a VXI A/B to C-Size Adapter that enables integration of smaller form-factor VXI modules into C-size VXI mainframes. This active adapter provides mechanical and electrical compatibility, allowing A- or B-size VXI modules to operate within C-size VXI infrastructure. It functions as a slave-only device, making it ideal for upgrading legacy test systems or incorporating compact modules into contemporary VXI platforms without requiring wholesale chassis replacement.

– Technical Specifications

• Module Type: VXI A/B to C-Size Adapter
• Form Factor: Adapts A- or B-size VXI modules for C-size VXI mainframes
• Slot Configuration: Standard 1-slot width; optional 2-slot width (Option 010) available
• Backplane Connection: 2-slot option connects on the left-most slot
• Primary Interface: P1 connector with active buffering and extension
• Capability: Slave-only operation; cannot be used in Slot 0 or with bus masters
• Signal Support: SUMBUS signals with jumper-selectable sourcing from module or mainframe backplane
• Interrupt Support: Supports IRQ (Interrupt Signals)
• Multiple Unit Operation: Unlimited adapters can be deployed within a single C-size mainframe
• Electrical Compliance: Meets VMEbus driving and loading specifications

– Key Features

• Fully buffered P1 connector extension maintains signal integrity across the adapter interface
• Active component derives power from the VXI backplane
• Flexible SUMBUS jumper configuration accommodates diverse signal sourcing requirements
• Supports IRQ signal routing for interrupt-driven applications

– Typical Applications

• Legacy VXI module integration into modern C-size chassis
• Test system expansion without mainframe replacement
• Mixed form-factor VXI deployments

– Compatibility & Integration

Designed for all C-size VXI mainframes. Compatible with A- and B-size VXI modules operating in slave mode. VME modules meeting VXI mechanical and electrical restrictions may interface with the adapter, though such configurations are not officially supported. The adapter cannot function in Slot 0 or in any bus master role.
