Keysight N8836A PAM-4 Measurement Application For Infiniium S-Series, 90000A, V-Series, 90000 X-Series, 90000 Q-Series, and Z-Series Oscilloscopes

2021-04-19
Several industry groups and standards bodies are using (or actively considering) pulse amplitude modulation 4-Level (PAM-4) technology to jump to the next-generation speed class. PAM-4 signaling enables higher throughput for a given channel bandwidth compared to traditional non-return-to-zero (NRZ) signaling.
Working groups within the Optical Internetworking Forum - Common Electrical Interface (OIF-CEI 4.0) and IEEE 400G Ethernet (P802.3bs) are leveraging many of the PAM-4 measurements outlined in IEEE P802.3bs. Examples of standards or Implementation Agreements (IA) that propose PAM-4 signaling include:
●IEEE 400G Ethernet (P802.3bs)
●OIF-CEI-4.0 (56G)
■OIF-CEI-56G-XSR-PAM4 (Extra Short Reach interface)
■OIF-CEI-56G-VSR-PAM4 (Very Short Reach interface)
■OIF-CEI-56G-MR-PAM4 (Medium Reach interface)
■OIF-CEI-56G-LR-PAM4 (Long Reach interface)
While the PAM-4 parameters are still in the development stages, companies are moving forward with their PAM-4 development and need measurement tools to help analyze their designs quickly and accurately.
