1. An arrangement for signal analysis, comprising:
at least one central data-processing unit; and
a screen unit connected to the at least one central data-processing unit, wherein the central data-processing unit calculates a spectrum and a spectrogram from a digitised signal,
wherein the at least one central data-processing unit controls the screen unit so that the spectrogram of the digitised signal, a representation of the spectrum of the digitised signal, and a representation of the digitised signal present in the time domain can be displayed together on the screen unit, and
wherein the spectrogram of the digitised signal is displayed on the screen unit in a first diagram and the representation of the spectrum of the digitised signal is displayed in a second diagram by the at least one central data-processing unit at the same time on the screen unit.
