Latest module for market-leading signal quality analyser

Anritsu's new 64 Gbaud PAM4 PPG is installed on the Signal Quality Analyzer-R MP1900A series. The device is a quality-evaluation test solution for measuring the bit error rate of the highest-level signals targeted for use by next-generation, high-speed 400/800GbE communications. The series is a high-performance BERT that accurately measures communications equipment, next-generation high-speed electronic and optical devices, incorporating those for M2M and IoT applications, and optical transceivers used in high-end servers. The 53.125-Gbaud high-speed PAM4 transmission method under discussion to implement 400GbE implies several challenges: short pulse width per bit to 18.8 ps, one-third level transition amplitudes compared to NRZ signals, more complex detection which require much longer time and higher electrical potential accuracy. Achieving device and module bit error rate testing with high accuracy and good reproducibility under these conditions needs a great reference signal source, and a measuring instrument with excellent high frequency and wideband performance, low noise and superior input sensitivity.
