1. A method for determining a deviation of a broadband measurement signal from a reference signal, comprising:
subdividing, by a signal subdividing circuit, the [ a ] broadband measurement signal into at least two [ a plurality of ] subband measurement signals;
displacing, by a signal alignment circuit, the at least two subband measurement signals to correspond with respective frequency bands of the [ a ] reference signal , wherein the displacement is performed with the use of an external trigger signal; and
reconstructing, [ generating, ] by a signal reconstruction circuit, the at least two subband measurement signals to form a reconstructed broadband measurement signal [ based on the displaced subband measurement signals, wherein the generation of the reconstructed measurement signal is performed with the use of an external trigger signal; and
analyzing the reconstructed measurement signal relative to the reference signal, wherein a deviation of the reconstructed measurement signal relative to the reference signal is used as a value for performing an error determination] .
