Protocol Analyzers & Exercisers

Deep insight at higher speeds

Effective Solutions to Debug, Validate, and Optimize

Keysight protocol analyzers and exercisers offer an advanced verification system that allows you to capture the data traffic generated by various protocols, such as PCI Express (PCIe), Advanced Switching Interconnect (ASI), and Fibre Channel (FC). They also enable you to view and analyze the captured data to identify problems, find their root cause, and troubleshoot them. This makes protocol analyzers a very effective tool to control as well as speed the development and testing of the PCIe, ASI, and FC protocols.
