Curtiss-Wright / VMETRO VXE-35C VXI Extender Board

The Curtiss-Wright / VMETRO VXE-35C is a VXI extender board engineered to expand VXI backplane configurations while maintaining signal integrity across the entire system. This adapter enables larger, more complex test and development environments by extending VXI functionality and isolating non-TTL signals from the backplane—a critical requirement in systems operating beyond standard TTL/CMOS voltage levels.

## Technical Specifications

**Manufacturer:** Curtiss-Wright / VMETRO
**Model:** VXE-35C
**Product Type:** VXI Extender Board
**Form Factor:** C-size VXI systems

## Key Features

• Expands VXI backplane to support larger system configurations
• Maintains full VXI specification compliance across extended architectures
• Isolates non-TTL signals on the P2 bus, essential for voltage levels exceeding standard logic thresholds
• Serves as adapter for the VMETRO VBT-325C VMEbus Analyzer, enabling VXI analysis capabilities
• Preserves signal integrity critical for reliable data transfer in extended VXI systems
• Specifically designed for deployment in C-size VXI chassis

## Typical Applications

• VXI system expansion requiring increased slot count and modular flexibility
• VMEbus analyzer integration into VXI test environments
• Systems requiring isolation of mixed-signal or analog components with non-standard voltage levels
• Development and validation platforms requiring extended VXI backplane access

## Compatibility & Integration

The VXE-35C interfaces directly with the VXI backplane and functions as a dedicated adapter for the VMETRO VBT-325C VMEbus Analyzer. This pairing allows the VBT-325C to operate within C-size VXI systems while isolating signals with illegal voltage levels on the P2 bus. The extender maintains backward compatibility with full VXI specifications, ensuring seamless integration into existing test frameworks. Extended lifecycle support is available through third-party suppliers.
