Modern PC hardware is real RF voodoo these days: DDR5 runs at 5+ GHz, PCIe 5.0 runs at 16 GHz (!!), networking/SFPs running at 26+ GHz, often using advanced modulation like PAM4. All of those ultra high speed links are doing some form of equalization/link training and their hardware is very often capable of measuring/reporting eye diagrams.
