The Curtiss-Wright/VMETRO Vanguard-PMC is a PMC (PCI Mezzanine Card) form factor bus analyzer and exerciser delivering real-time state analysis, protocol checking, and performance statistics for PCI and PCI-X embedded systems. The module captures and analyzes up to 93 bus signals plus 16 external inputs, supporting signaling up to 133 MHz across both 3.3 V and 5 V levels. Advanced triggering, filtering, and counting capabilities enable detailed bus activity capture and bottleneck identification. Dual DMA engines, target memory spaces, and flexible scripting support concurrent test automation and system validation.
