Archivio Istituzionale della RicercaIn this work the calibration of the magnitude error and the noise response of a digital lock-in amplifier are presented. A simple but effective calibration setup developed at INRIM is used to assess the magnitude error of a recent model of lock-in amplifier. The noise response of the instrument is analyzed in terms of Allan deviation for different filter orders.

Abstract
In this work the calibration of the magnitude error and the noise response of a digital lock-in amplifier are presented. A simple but effective calibration setup developed at INRIM is used to assess the magnitude error of a recent model of lock-in amplifier. The noise response of the instrument is analyzed in terms of Allan deviation for different filter orders.
