800G research is well under way and alternate modulation methods are at the forefront of higher speed signaling schemes. Whether industries settle on 96 Gbaud PAM6 or 112 Gbaud PAM4 is still undecided. The combination of a UXR-series oscilloscope with a software CDR provides the flexibility needed to address the potential new modulation formats, while also providing real-time access to timing information. Core optical measurements such as TDECQ are possible when using the combination of software CDR, UXR-series oscilloscope, and FlexRT software. For more information visit https://keysight.com/find/800G
