S-parameter resonance method for the calibration of standard capacitors

National Metrology Institute of Turkey (TÜBİTAK UME) has developed a new approach for the characterization of Agilent 16380A-type four-terminal-pair (4TP) air dielectric capacitance standards in the range of 1 pF to 1000 pF up to 30 MHz. This method is based on determining all residual inductive parameters of 4TP standard air dielectric capacitors from resonance frequencies. These resonance frequencies were calculated using impedance and admittance values obtained from scattering parameter measurements up to 500 MHz employing a vector network analyzer. Capacitive residual parameters were measured by using a 1 kHz capacitance bridge.
