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.

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.
