| Abstract: | In connection with comparisons, planned by the International Bureau of Weights and Measures (in conformity with the BIPM.EM-K10 Technical Protocol of Comparisons), of the AC and DC voltage standards based on the Josephson quantum effect, we study the possibility of application of a programmable Josephson voltage array from the State Primary Standard of the Unit of Electric Voltage GÉT 13-2023 for measuring sinusoidal voltages of 0.75 and 7 V within the frequency range 62.5–1000.0 Hz. In the case of measuring voltages within the frequency range 62.5–200 Hz, parallel with the quantum voltage standard, we use a digital voltmeter with specially developed software for measuring AC voltage. The obtained results differ from the results of measurements presented in the Technical Protocol of Comparisons. However, the results of the performed investigations confirm the possibility of application of the quantum voltage standard based on the programmable Josephson array from the composition of GÉT 13-2023 for the purposes of comparisons based on the indicated Technical Protocol. We analyze the interaction of the quantum voltage standard with the AC voltage source and make a conclusion that it is necessary to perform monitoring of the reproduced AC voltage with the help of a digital voltmeter equipped with software recommended in the Technical Protocol for comparisons.
