A device for machine diagnostics, with a vibration sensor (12) for detecting vibration signals on the machine (10), a unit (14) for conditioning the vibration signals, an A/D converter (16) for digitizing the conditioned vibration signals, a data processing unit (20) for splitting the digital signals into at least two frequency ranges, the data processing unit being made to scale the signal for each frequency range to an amplitude resolution which is less than the amplitude resolution of the A/D converter, and an evaluation unit (30) for further evaluation of the split signals.
