AC resistance measurements using digital sampling techniques

Vasconcellos, Renata Teixeira de Barros e; Ihlenfeld, Waldemar Guilherme Kurten (2015)

Here we will present measurement results for ac resistors calibrations, made with a four terminal-pair digital impedance bridge, developed at Inmetro. This bridge operates in a wide frequency and value ranges, for both ...
Design of a digital four-terminal-pair impedance bridge

Ihlenfeld, Waldemar Guilherme Kurten; Vasconcellos, Renata Teixeira de Barros e (2015)

The paper describes the design of a four-terminal-pair impedance bridge developed at INMETRO. Originally devised to work as a quadrature bridge for deriving the unit of capacitance (Farad) from a resistance (Ohm) or ...
