Transmission line losses—driven by skin effect and dielectric properties—play a critical role in degrading high-speed signal integrity and eye performance.
Transmission line loss directly affects eye diagram quality, with around −12 dB at Nyquist marking the limit before signal integrity rapidly degrades without equalization.
Deep dives into high-speed PCI Express signaling, compliance testing, and performance analysis across generations. Covers oscilloscope-based electrical compliance testing and cross-layer (electrical and protocol) analysis for debugging complex problems.
Understanding PCIe’s layered architecture reveals why capturing synchronized physical- and protocol-layer behavior is essential for effective link debugging.
PCIe 6.0’s move to PAM4 signaling introduces new compliance pattern measurements—SNDR, RLM, and ps21TX—that require updated test methodologies and noise-aware analysis.
PCIe 6.0 compliance requires SNDR and RLM results with oscilloscope noise removed—these three methods show how to compensate noise accurately in real test setups.
