There is a matched load at the end of the line (this means that there is no reflection at the end, so there is only a signal traveling in the + z direction). At the input of the line, a sawtooth waveform is applied, having a peak voltage of 1.0 [V] and a duration of 1.0 [ns] (the time from the beginning of the waveform until the end).
