    A Quadrature Bridge for QHE-Based Calibration of Capacitance Standards

  • Original language description

    A method is described which utilizes a 12906.4 Ohm resistor as a reference standard for capacitance calibrations. DC value of this resistor being obtained by comparing it against a resistor having calculable frequency performance. Subsequently, the reference resistor and a 10 nF capacitor are linked by means of a quadrature bridge based on a commercial two-phase generator. The 10 nF capacitor, in turn, serves as a reference standard for calibration of capacitors of lower values by means of a four terminal-pair transformer bridge. By means of the quadrature bridge, capacitance can be measured with a standard uncertainty of less than 30 ppm in the frequency range from 400 Hz to 5 kHz at the 10 nF level.
