Application of a Calorimetric Thermal Converter as a Standard of Acdc Voltage and Current Transfer Difference

At the National Research Council of Canada (NRC) the primary standard of AC-DC transfer difference at frequencies from 10 kHz to 100 MHz is a Calorimetric Thermal Voltage Converter (CTVC). Because of a simple design, not unlike a coaxial calorimeter for RF power measurements, its frequency characteristic can be estimated theoretically from a number of… CONTINUE READING
