With PAM-4 data format support and built-in error counters, M8000 Series helps engineers characterize and test high-speed digital receivers for data-center networking, storage, and computer industries. Solution consists of AXIe-based BERT and arbitrary waveform generator modules that are controlled from common user interface software. Users can generate PAM-4 patterns up to 32 Gbaud symbol rate and up to 4 channels with M8195A arbitrary waveform generator, and NRZ patterns with J-BERT M8020A.
