Calibration of bridge-, charge- and voltage amplifiers for dynamic measurement applications

Measuring amplifiers are used for transducer output signal conditioning in many dynamic measurement applications. For a traceable measurement, a calibration of all components of the measuring chain-and therefore of the conditioning amplifiers, too-is mandatory. In this paper methods for a dynamic calibration of different types of conditioning amplifiers are presented. Measurement uncertainties and calibration results for typical amplifiers are discussed.
