International comparisons at low voltage (0.001 V) and high voltage (100 V) in coaxial line at 30 MHz

At a frequency of 30 MHz, (i) two micropotentiometers (0.001 V) have been intercompared between ASMW, OMH, NIM, NIST, NPL (India), PTB, TF and (ii), in a second exercise two thermal converters (100 V) between NIST, NPL (India) and PTB. In this paper, the methods for determining the RF-DC transfer difference are described and the results of the intercomparisons are presented.<
