Our Publications

Due to a decision of the Consortium made during the Kick-Off meeting this page is intended to give a comprehensive overview of publications authored or co-authored by members of the consortium and related to the topic of traceable dynamic measurement.

Note: not all of the listed publications have been published within the framework of the EMRP, therefore, not all of the publications listed here were produced with the support of funding from the European Union on the basis of Decision No 912/2009/EC.

Abstract: This contribution discusses the influence of the source impedance on the complex sensitivity of a charge amplifier (CA). During calibration of a CA with varying source impedances deviations at higher frequencies were observed, which if not properly taken into account may generate systematic errors beyond the limits of the measurement uncertainty budget. The contribution discusses a model to describe the effect as well as an extension to established CA calibration procedures which allow to quantify and correct the effect.
