get_all_sparameter_list# property Circuit.get_all_sparameter_list# List of all S parameters for a list of excitations. Parameters: excitation_nameslist, optionalList of excitations. The default is None, in which case the S parameters for all excitations are to be provided. For example, ["1", "2"]. Returns: listStrings representing the S parameters of the excitations. For example, ["S(1, 1)", "S(1, 2)", S(2, 2)].
