The Curtiss-Wright/VMETRO Vanguard-PCI is a PCI and PCI-X bus analyzer and exerciser designed for hardware and software development, validation, and troubleshooting. It captures and analyzes PCI bus transactions in real time, supporting both PCI and PCI-X protocols up to 133 MHz. The instrument operates via a Windows-based PC interface using the BusView graphical user interface or an application programming interface (API), and connects through 10/100 Mbit/s Ethernet or USB.
## Technical Specifications
• **Analysis Bandwidth:** 64-bit or 32-bit bus activity capture up to 133 MHz
• **Trace Buffer:** 2M Sample Trace Buffer @ 256-bits
• **Protocol Support:** PCI (0–66 MHz), PCI-X (0–133 MHz), CompactPCI (cPCI), PMC (Peripheral Module)
• **Form Factors:** PCI Short Card, cPCI (System Slot or Peripheral), PMC; zero-slot adapter available for PCI systems
• **Host Interfaces:** 10/100 Mbit/s Ethernet, USB
• **Power:** 5V Adapter Card draws 33 mA @ 3.3V; LED display powered from 5V rail
## Key Features
• **State Analyzer** — Captures PCI-X/PCI bus activity with advanced triggering, filtering, and counting; three sampling modes: Standard, Clock, and Transfer
• **Protocol Checker (Optional)** — Detects protocol errors: up to 71 errors for PCI-X, up to 45 errors for PCI; operates in background and triggers on error events
• **Statistics Functions** — Real-time measurement of latency, throughput, and device efficiency
• **Dual DMA Engines** — Concurrent DMA operation with target memory (I/O and memory spaces)
• **Command Executer** — Device emulation and custom bus traffic generation
• **Scripting Support** — Automated test scenario creation and execution
• **Advanced Exerciser (Optional)** — Bus Master with DMA, Target interface with 8 MB memory, and Interrupter; supports 32-bit/64-bit at 66 MHz PCI and 100 MHz PCI-X
## Typical Applications
Protocol validation, device driver debugging, PCI/PCI-X subsystem characterization, and automated regression testing of embedded and enterprise systems.
## Compatibility & Integration
Available in multiple form factors including optional 6U cPCI adapter (CPCI-3U6U-ADA). Powered from target system or external supply (external supply required for Vanguard cPCI).
