Excitation offset frame
The temporal shift between the excitation signals of simultaneous stimulated ports can be characterized either by a time shift or a phase shift. The phase shift setting requires a phase reference frequency: The phase values defined in the excitation list above are converted into corresponding time shifts for the time signals by use of this reference frequency. For example, a broadband phase shift of 180 degrees can be achieved by: amplitude = -1 and phase = 0.
