A FOUR TERMINAL-PAIR COAXIAL IMPEDANCE BRIDGE CONSTRUCTED AT INMETRO

Renata T. de Barros e Vasconcellos, Luiz Macoto Ogino
  • Abstract:
    This paper describes the final construction stage and preliminary measurements results of a low-frequency four terminal-pair coaxial impedance bridge, part of the traceability chain of the capacitance unit to the quantum Hall effect, constructed at Inmetro. The coaxial bridge is a complex system, with several technical advantages, as highstability and very low-uncertainty.
