Abstract
A differential probe provides a probe input which comprises two inputs for recording a first and second input signal. The differential probe further provides a first amplifier which is connected to the two inputs. The differential probe additionally provides a compensation device, which generates and superposes on the first and second input signal a differential offset signal. The compensation device also generates a common-mode offset signal which is independent of the differential offset signal.
