HIGHLIGHTS

Electrical signals

Eye width, eye height, eye skew
Level amplitude, level noise, level skew
Bit error ratio and symbol error ratio measurements (Trigger on burst errors and unfold eye to show BER/SER error in PAM-4 waveform)
Linearity measurements and more

Powerful analysis features

PAM-4 equalizers (LFE, CTLE) using the N5461A Infiniium serial data equalization software
Embedding / de-embedding of channels using the N5465A InfiniiSim waveform transformation toolset for Infiniium oscilloscopes
Jitter and amplitude analysis on JP03 patterns using the N5400A EZJIT Plus jitter analysis software

Flexible, economical

PAM features integrated directly into the Infiniium graphical user interface (not a separate application)
Offline analysis on a PC using saved or simulated PAM-4 waveforms running N8900-003 Infiniium Offline analysis software bundle

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

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.
