Description
Demand for increased network bandwidth in data centers continues to grow. Pulse Amplitude Modulation (PAM) is a multi-level signaling format that is enabling technology to help address this need. The switch from NRZ to PAM-4 is revolutionary, rather than evolutionary from 100G, presenting many new design and measurement challenges. The Keysight N8827B PAM-4 analysis software for Infiniium real-time oscilloscopes is designed to accurately and quickly characterize PAM-4 electrical signals described in IEEE 802.3bj Clause 94 and address future PAM measurement needs as outlined in developing standards such as OIF-CEI-56G and IEEE 400G.
