      uSimmics 5.9

      I simulate a coax cable in the frequency range 10 MHz to 20 GHz with 10 MHz steps. The S-parameter looks good.

      If I plot the time domain signal according to the minimal description I get the error on the diagram.
      Have I done something wrong, or is this a bug?

        Hi el-spec_SB,
        freq2time appears to require the DC point. If you start the sweep at zero Hz, it should work as intended.
