Cable Correction Model for HF Resistance Standards Comparisons
Original language description
In this article, we present a model that allows for significantly improving the impedance accuracy of calculable resistance standards. The proposed model extends the correction factor applied to the calculated four-terminal-pair impedance from the connector parts of the standard to the complete measurement circuit concerned by the applied voltage and current, respectively. In particular, we consider the cables and connectors contribution of the impedance bridge electronics. The model has been validated by performing: 1:1 and 0.1:1 impedance comparisons by means of two different typologies of calculable resistance standards. For the measurements, we relied on the accuracy of a digital bridge, which exploits the signals of two Josephson arbitrary waveform synthesizers (JAWSs). The frequency dependence of these new resistors has been analyzed over a range between 1 and 80 kHz.
