• Protocol Checker and Exerciser
• 2-MSample Trace Buffer at 256 bits
• Concurrent, independent operation of all functions

The Vanguard PCI Bus Analyzer is an all-in-one PCI/PCI-X solution, handling debugging, analysis, protocol detection, exercising, and compliance checking.

With a 10/100 Mbit/s Ethernet interface, the Vanguard PCI takes the recognized power and flexibility of Curtiss-Wright Bus Analyzers to an unprecedented level of excellence and productivity. Controlled from a PC running Windows and BusView graphical user interface, or an Application Programming Interface (API), the Vanguard PCI Analyzer supports PCI and PCI-X protocol and signaling. The PCI form factor shares a common hardware module—called the State Analyzer Module (SAM)—with the PCI0SL and CompactPCI form factors. The SAM is interchangeable between the carrier boards.

State Analyzer
The Vanguard PCI’s State Analyzer captures and displays 64- or 32-bit PCI-X/PCI bus activity up to 133 MHz with highly advanced, easy to use filtering, triggering and counting capabilities. The state analyzer offers options of three sampling modes—Clock, Standard and Transfer—to provide the most appropriate bus analysis for a given problem.

Exercisers
The basic and enhanced Exerciser versions available for the Vanguard PCI Analyzer offer users the advantages of flexibility and ease of use. They allow two DMA engines, a target memory with I/O and memory spaces, and a command executor to operate concurrently. The Exercisers’ flexible script feature automates tasks and allows test scripts to be created.

Protocol Checker
The Vanguard’s optional protocol checker for PCI-X and PCI runs in the background when other analyzer functions are active. It automatically detects up to 71 PCI-X and 45 PCI protocol errors, helping the user track down bus hardware errors without having to understand the nature of the issue. The state analyzer and bus utilization statistics, for instance, can be active while the protocol checker screens the bus for errors in the background. When the protocol checker serves as the trigger source for the analyzers, the Vanguard’s state and timing analyzers provide a comprehensive picture of the bus activity around the point of an identified error. This assists the user in identifying and fixing the problem.
