What is PCIe gen 6 and how do I test it? Part 2
PAM4 modulation boosts throughput but adds test challenges. Part 1 of this two-part series described the evolution of the PCI Express (PCIe) standard, including the move from non-return-to-zero (NRZ) signaling in PCIe 5 to four-level pulse-amplitude modulation (PAM4) signaling in PCIe 6. What unique test challenges does PCIe 6 present? As mentioned in Part 1, […]
What is PCIe gen 6 and how do I test it? Part 1
PAM4 modulation boosts throughput but adds test challenges. The Peripheral Component Interface (PCI) emerged in the 1990s as a parallel bus for connecting computer mainboards and peripheral devices. In 2003, a serial version called PCI Express (PCIe) debuted, with generation 1 offering a transfer rate of 2.5 GT/s. Over the past 20 years, successive generations […]
