Keysight / Agilent / HP E1403B VXI A/B to C-Size Adapter

The Keysight E1403B is a VXI adapter module that enables A/B-size VXI and VME instruments to operate within C-size VXI mainframes. It provides active P1 connector extension and slave-only functionality, allowing smaller form-factor modules to integrate into larger chassis environments without requiring bus master capability.

– Technical Specifications

• Form Factor: Adapts A- or B-size modules for C-size VXI mainframes
• Slot Width: 1-slot standard configuration; 2-slot wide option (Option 002) available
• Interface: Active P1 connector extension
• Operating Mode: Slave-only (cannot function as VXI system controller)
• Slot Restrictions: Cannot be installed in Slot 0 or with bus masters
• Mainframe Capacity: Unlimited number of adapters per C-size VXI mainframe
• Shipping Weight: Approximately 3 lbs
• Physical Dimensions: 9 × 12 × 15 inches

– Key Features

• Active electrical extension of P1 connector ensures proper signal integrity between A/B-size modules and C-size mainframe backplane
• Dual configuration options accommodate both standard and space-constrained installations
• Mechanical and electrical interface compatibility with all C-size VXI mainframe architectures
• Supports unlimited quantity per system for maximum modularity

– Typical Applications

• Integration of B-size digital I/O modules (such as Agilent E1330B Quad 8-Bit) into C-size mainframes
• Expansion of existing VXI systems with legacy or specialized A/B-size instruments
• Laboratory and enterprise measurement configurations requiring flexible module placement

– Compatibility & Integration

The E1403B is fully compatible with C-size VXI mainframes including the Agilent E1401B. As a slave-only adapter, it operates under control of a VXI system controller located elsewhere in the mainframe. Compatible B-size modules plug directly into the adapter’s P1 extension without additional interfacing.
