Calibration device, signal processing device, and user interface for the same

Method, performed by a calibration device, for calibrating a signal processing device comprising an input stage, a signal processing stage and an output stage, comprising:

• calibrating the output stage with the substeps providing a test signal to the output stage, returning the test signal to the input stage after processing by the output stage and analyzing the test signal after processing by the input stage to determine deviations of an actual output amplification of the output stage at a set output amplification of the output stage and/or deviations of an actual input amplification of the input stage at a set input amplification of the input stage,
• wherein the method comprises the step of calibrating the input stage prior to calibrating the output stage,
• wherein calibrating the input stage comprises the substeps of providing a calibration signal to the input stage and analyzing the calibration signal after processing by the input stage, in order to determine deviations of an actual input amplification of the input stage at a set input amplification of the input stage,
• wherein the deviations of the actual input amplification are considered in the step of calibrating the output stage.
