Trilateral Comparison of a Planar Thin-Film Thermal AC Voltage Standard in Frequency Range 1 MHz - 30 MHz

The paper presents results of a trilateral comparison of a travelling AC voltage standard, which was a fused-silica NIST planar multijunction thin-film thermal converter. The AC-DC voltage transfer difference of the standard was measured at 2 V and selected frequencies from 1 MHz to 30 MHz against primary thermal AC voltage standards at SUT, RISE and Trescal.
