Training Description: PSD Power Spectral Density Calibration of PLC-Modems

PSD power spectral density calibration of PLC modems according to ISO15118-3 for EV and EVSE

In the first part of this training, we discuss the hardware for the Power-Line-Communication PLC.

The second part deals with the Signal Level Attenuation Characterization SLAC. You will learn about SLAC functionality as well as the calibration of the SLAC.

You will get to know the PSD power spectral density calibration of PLC modems according to ISO15118-3 for electric vehicle EV and charging station EVSE.
