D8: Report on the calibration of a capacitance standard at the level of 100 pF using digitally-assisted bridges, build-up methods and digital bridges, which is suitable for dissemination, with an overall uncertainty of 5 × 10−7 or lower at a frequency around 1 kH

Popis výsledku v původním jazyce

One of the scientific and technical objectives of the project 18SIB07 GIQS is to provide realizations of the farad by means of fully-digital impedance bridges, based either on polyphase electronic waveform synthesizers (at CMI, INRIM and KRISS) or on two Josephson arbitrary waveform synthesizers (at METAS and PTB), starting from graphene ACQHR standards. Impedance bridges of these kind, compared to quadrature transformerratio bridges, are easier to implement and operate, making them suitable and affordable by a broader range of laboratories, from national metrology institutes to calibration laboratories. This report deals wit calibration of a capacitance standard at the level of 100 pF using digitally-assisted bridges, build-up methods and digital bridges, which is suitable for dissemination, with an overall uncertainty of 5 × 10−7 or lower at a frequency around 1 kHz.
