Keysight demos a full PAM4 E-O-E (Electrical – Optical – Electrical) end-to-end link simulation example in PathWave ADS 2022, including modeling of the optical channel using VPIphotonics’ VPItransmissionMaker™. The connected solution to FlexDCA allows fast and accurate insights of PAM4 measurements, comparison with measured results including transmitter dispersion and eye closure quaternary (TDECQ) and access to a variety of compliance test solutions.
