Compatibility
 

  • Infiniium 90000A, V-Series, Z-Series (and discontinued 90000 Q-Series and X-Series) real-time oscilloscopes running firmware revision 5.6 or later

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 N8827A 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. In addition, the N8827A software tool allows you to perform bit error ratio (BER) and symbol error ratio (SER) for a continuous repeating pattern (such as a PRBS7) using PAM-4 signaling.
