The Ametek / VTI Instruments 33-0011-000 is a VXIbus communication board that enables data transfer and control within modular automated test equipment (ATE) systems. This board serves as a communication bridge, integrating multiple test and measurement modules across VXIbus mainframes while maintaining high-speed data handling and precise synchronization between system components.
Technical Specifications
VXIbus Architecture
The board operates within the VXIbus (VME eXtensions for Instrumentation) framework, a modular standard combining VMEbus performance with GPIB-level usability. It supports both message-based (Word Serial) and register-based (binary) communication protocols, enabling flexible module integration.
Data Transfer & Synchronization
Designed for high-speed data acquisition and processing, the board delivers precise timing synchronization across interconnected modules—critical for complex test sequences and data integrity.
Backplane Connectivity
Utilizes standard VXIbus connectors (P1 and P2). The P1 connector carries the VME and VXIbus data transfer bus; the P2 connector expands to full 32-bit operation and includes a 10 MHz clock bus and trigger buses.
– Key Features
• Standard VXIbus backplane integration (P1/P2 connectors)
• 10 MHz clock bus distribution
• Trigger bus support for multi-module synchronization
• Register-based and message-based device support
• Operates in C-size form factor (23.3 × 34 cm)
• Acts as control and configuration bridge within VXI mainframe
– Typical Applications
• Multi-module ATE system development
• High-speed test data acquisition
• Synchronized instrument control across VXI chassis
• Complex automated test sequences requiring precise timing
– Compatibility & Integration
Designed for seamless integration into VXIbus mainframes and systems. Enables construction of versatile ATE platforms by interconnecting a wide range of VXIbus instruments and measurement modules within a common backplane architecture.
