A Suitable Method to Obtain and Compare AC-DC Difference Loading Errors of Thermal Transfer Standards
T. H. Duong, Stefan Cular · 2024
This paper describes a suitable method to obtain and compare the loading effects of thermal transfer standards to obtain optimal values of input impedance and the AC-DC difference loading errors. The loading effects are evaluated with different values of source series-connected resistance and a bypass capacitance at desired frequencies and applied voltages. The results indicate that the AC-DC difference loading errors are minimized with a nominal source series-connected resistance value of 50 Ω, and a bypass capacitance value in the range of 33 pF to 68 pF.
