Abstract :
This paper presents the setup for investigating INMETRO´s programmable ac voltage standard with thermal converters. Of primary interest is the validation of differential ac voltage calibrations of the Josephson system with thermal converters and their calibration against the quantum system. Proposals for attaining these goals are presented.
