Abstract :
A precise measurement of the ratio of two cryogenic capacitors is needed for a capacitor charging experiment using single electron tunneling (SET) phenomena. To support the capacitor charging metrology a frequency characterization of the capacitors is required. To cover the frequency range from 1 Hz to 1 kHz, resistive and inductive voltage divider bridges are proposed. Preliminary tests suggest that the uncertainty with which the capacitor ratio can be evaluated is less than one part per 10/sup 6/.
