Four-terminal mutual inductor for calibration of the lock-in amplifier at mV ranges

This paper describes a method for calibrating the accuracy and linearity in quadrature part of the lock-in amplifier at mV ranges. The method is based on the use of the four-terminal mutual inductor and three-branch binary inductive current divider (BICD). The measurement standard uncertainties are...

Description
Summary:This paper describes a method for calibrating the accuracy and linearity in quadrature part of the lock-in amplifier at mV ranges. The method is based on the use of the four-terminal mutual inductor and three-branch binary inductive current divider (BICD). The measurement standard uncertainties are presented at frequencies from 20 kHz to 200 kHz.
