    I have a unexplained step in the phase plot (see first screenshot) which is not present in the imported file (second screenshot). The phase plot is saved as unwrapped and a closer look in datas shows no step. It seem to me the step is exactly 180° where the import file leaves the plot at ca. 150 Hz. Do you have an explanation for this behavior?

    Thanks and best regards
