  • 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 ...
  • Silva, Márcio Cândido da; Carvalho, Hélio Ricardo; Vasconcellos, Renata Teixeira de Barros e (2015)
    This paper presents a comparison results between the Quantum Hall System (QHS) under development at the Quantum Electrical Metrology Laboratory (Lameq) and the current comparator calibration system, traceable to the Bureau ...
  • 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 ...
