The Keysight U4305B is a PCIe protocol exerciser module that validates and debugs PCI Express devices and systems across Gen1, Gen2, and Gen3 speeds. Operating as either a root complex or endpoint emulator, it generates and responds to transaction layer packets, data link layer packets, and physical layer traffic. The module supports link widths from x1 to x16 and includes advanced capabilities for NVMe emulation, power management testing, LTSSM validation, and PCI-SIG compliance testing. Error injection, protocol checking, and data replay from captured analyzer sessions enable thorough device characterization. Control is provided via graphical user interface or APIs supporting TCL, Python, C++, and C# for automated test development and execution.
