Curtiss-Wright / VMETRO PBTC-415BX cPCI Bus Analyzer and Exerciser

The Curtiss-Wright/VMETRO PBTC-415BX is a single-slot CompactPCI bus analyzer and exerciser that mounts directly into a cPCI backplane for real-time monitoring and testing of bus activity. The card functions as both a passive analyzer - capturing all bus transactions without external probes - and an active exerciser, operating as a PCI bus Master and Target to generate and respond to nearly all PCI bus cycle types. Engineers use it to debug, validate, and characterize cPCI system performance with minimal setup complexity.
