Abstract

Collaboration of the Polish National Metrology Institute (GUM, Warsaw) with the Silesian University of Technology (SUT, Gliwice) and joint participation in international projects focused on the development of digital sources and digital impedance bridges contributed to the development of the impedance metrology infrastructure at GUM. The article presents current work related to expanding the current infrastructure with a new 4TP, mostly thermostated impedance standards terminated with MUSA connectors. Design solutions, results of thermal stability measurements and results of the comparison of new impedance standards made with the currently implemented digital impedance bridge are presented in the paper.
