摘要：The device of the present invention for digitalizing data comprises a powerdivider (5), having a first and second output (6, 7), wherein the power divider (5) divides ananalog input signal (4) into a first analog signal(8) which can be output to the first output(6) of a first signal branch having a first power fraction, and into a second analog signal (9)which can be output to a second output (7) of a second signal branch having a secondpower fraction. Furthermore, the first and the second output (6, 7) of the power divider(5) are connected to a first and second analog-digital converter (12, 13) each, so that thefirst and second analog signal (8, 9) can be digitalized each. A switching device (33)connects either the first or the second signal branch to a signal output (34). A controller(24) is disposed between the second analog-digital converter (13) and the switchingdevice (33) for adaptively adjusting at least the amplitudes of the second digital outputsignal (20) of the second analog-digital converter (13) to the amplitudes of the firstdigital output signal (19) of the first analog-digital converter (12).
