The paper presents steps taken to extend the frequency range of the thermal AC-DC voltage transfer maintained at SUT up to 10 MHz. The properties of the measurement setup are described after replacing the Fluke 5700A calibrator used as AC voltage source up to 1 MHz with the Fluke 6071A RF signal generator. Next the results of the consistency checking of the AC–DC transfer difference measurements performed with the new measurement setup is presented. The results of verification of the correctness of the calculated and measured AC–DC transfer differences of the two calculable thermal AC voltage standards are presented in 1–10 MHz frequency range. The inconsistency of the measured AC–DC transfer difference is below 55 μV/V at 10 MHz, when comparing PMJTCs with SJTC and below 25 μV/V when comparing PMJTCs among themselves. The AC–DC transfer difference of the SUT calculable AC voltage standard was calculated from the modified mathematical model for frequencies up to 10 MHz. Direct comparison of the 3 V calculable AC voltage standard with the 5 V one confirmed correctness of the results obtained from the mathematical model.
