There is a new compelling, high-performance solution that solves real customer problems and makes 448 Gbps testing a reality – today.
What’s New: M8159A FDIU
This is not just a hardware add-on. The M8159A is the enabler for pushing the M8199B platform into next-generation bandwidths. It allows you to:
- Extend available bandwidth to 120 GHz
- Enable testing beyond 224GBaud PAM4 and 240 GBaud 16QAM
- Confidently validate signals at 448 Gbps using PAM4, PAM6, and PAM8
- Combine with external amplifiers and DCA-X and/or UXR scopes for full-path signal validation
If you are in high-speed R&D, you need a way to generate and verify signals up to 448 Gbps—but all platforms top out. Keysight’s new solution – M8199B + M8159A – gives you a path forward.
