A new short-bar method for 4TP admittance standards calibration by using modified Z-matrix expression to improve S/N for higher impedance

open access: closed2008 Conference on Precision Electromagnetic Measurements Digest, 2008
This paper describes how to calibrate four-terminal-pair (4TP) admittance standards using a new short-bar method with modified Z-matrix expression containing a correction term. The short-bar method is to measure the signal to correspond to the standard with better S/N for higher impedance standard, especially 1 pF.

Establishment of 4TP air-dielectric capacitance standard for 1 pF, 10 pF, 100 pF and 1000 pF in the frequency range up to 30 MHz at NIMT

open access: closed2020 Conference on Precision Electromagnetic Measurements (CPEM), 2020
The 4TP air-dielectric capacitance standards have been evaluated successfully for the establishment of metrological traceability of capacitance standards at high frequency, and also the calibration measurement capabilities are suitable for supporting customer needs in Thailand.
