Automated PAM4 Compliance for 50G to 400G Ethernet
This datasheet presents the Keysight N4917BSCB solution for stressed-receiver sensitivity and jitter testing of PAM4 optical transceivers. It supports 50G, 100G, 200G, and 400G Ethernet variants under IEEE 802.3bs, 802.3cd, and 802.3db, including DR, FR, LR, and SR interfaces. The system combines a BERT, arbitrary waveform generator, optical reference transmitter, tunable laser, attenuator, and digital sampling oscilloscope. Software automatically calibrates stressed optical eyes using extinction ratio, optical modulation amplitude, SECQ or TDECQ, jitter, inter-symbol interference, sinusoidal interference, and Gaussian noise. Unified instrument control, adjustable targets, repeatable PAM4 calibration, DUT scripting, and automated reports help engineers validate receiver performance, intero
