Comparison of the frequency dependence of capacitance ratios between LNE and PTB

This paper describes a comparison of the frequency dependence of two capacitance ratios using newly developed impedance bridges from LNE and PTB. LNE designed an IVD based setup, whereas PTB used its Josephson impedance bridge for the measurements. Results are shown for 1:1 and 1:10 measurements from 60 Hz to 5 kHz and 60 Hz to 1.6 kHz, respectively.
