Ab st ra c t – A 10 Ω quadrifilar resistor with calculable frequency dependence served as a reference in measurement of frequency dependences of resistance standards ranging from 1 Ω to 0.01 Ω in a frequency range up to 10 kHz. In this measurement, a step-down method based on successive 10:1 comparisons of the standards by means of a transformer bridge was(More)
 Four terminal-pair coaxial capacitance standards with nominal values of 1 pF and 10 pF have been realized and, using a uniform transmission line model, their frequency dependences have been evaluated. 1:1 comparisons against reference capacitors with known frequency dependence (Agilent 16381A and Agilent 16382A) have shown that the values of the 1 pF and(More)
