Abstract
A probe system for registering a differential input signal has a first input network, which is supplied with a first component of the differential input signal in order to generate a first intermediate signal, and a second input network which is supplied with a second component of the differential input signal in order to generate a second intermediate signal. A differential amplifier for the amplification of the difference between the intermediate signals is arranged in the signal flow direction downstream of the input networks. At least one compensation network is used to compensate the influence of the input networks and is arranged at the output end of the differential amplifier or in a feedback path connecting an output to an input of the differential amplifier.
