As network bandwidth needs continue to rise, PAM4 (4 level pulse amplitude modulation) is emerging as a key enabler to meet this need. With 2 bits per symbol, 4 symbol levels, and 3 eye diagrams per UI, PAM4 presents many new measurement and testing challenges.
Tektronix, at the leading edge of signal fidelity, works in collaboration with datacom engineers and standards organizations to help pioneer the measurement techniques needed to perform PAM4 Tx and Rx characterization up to 112Gbps/56Gbaud for emerging OIF-CEI and IEEE PAM4 standards.
Learn valuable information on PAM4 technology along with Tektronix’ testing approaches for validating the PAM4 signal properties. This application note describes PAM4 technology for 50-400G applications, provides details of PAM4 signaling, outlines electrical and optical transmitter evaluation, explains methods for evaluating PAM4 receivers and more.
This webinar presents measurement techniques for PAM4 Data Communications and is useful for engineers involved in designing and developing 28G, 56G or 100G components, modules and systems.
