“…The loss factor of the reference capacitor is lower than 1 × 10 −5 (and also lower than the loss factor uncertainty of the commercial bridge) and this is the main uncertainty contribution to the loss factor of the capacitor under test. The loss factor of the reference capacitor could be determined by other methods with an uncertainty of about 2 × 10 −6 [28].…”

We present a simple and accurate coaxial bridge capable of measuring the magnetocapacitance and the associated loss factor of a quantum Hall effect device, with and without an external Hall current-a situation where commercial instruments are limited. We interpret the results in terms of the model of compressible and incompressible regions in the two-dimensional electron gas and we deduce a novel empirical relation between the loss factor and the voltage dependence of the magnetocapacitance. This highlights the reason for the linear voltage dependence of the loss factor whose elimination is the basis for all metrological applications of the quantum Hall resistance at alternating current.

The amplitude and the phase of a measured singletone signal can accurately be calculated from the discrete Fourier transform (DFT) components in case of coherent sampling. When the synchronization is not perfect, spectral leakage appears and errors are introduced in the determination of the signal parameters. In this paper, a new method to synchronize the sampling frequency with the frequency of the measured signal is presented. The method is based on the information contained in the fundamental and the sideband components of the DFT of the measured signal. A single measurement gives the synchronization error and permits the correction of the sampling frequency required to become coherent. Moreover, the error on the amplitude measurement relative to a quasi-coherent sampling is also discussed and quantitatively modeled. The results of the model as well as the synchronization process are experimentally verified and compared with the interpolated DFT algorithm.
