AC Voltage Measurements up to 120 V With a Josephson Arbitrary Waveform Synthesizer and an Inductive Voltage Divider
Ilya F. Budovsky, Dimitrios Georgakopoulos, Samuel P. Benz
We use a precision inductive voltage divider and a lock-in amplifier to extend the voltage range of a Josephson Arbitrary Waveform Synthesizer (JAWS) with a maximum voltage of 250 mV rms to provide accurate voltage measurements up to 120 V. Experimental results show that the output of the JAWS can be extended to high voltages with uncertainties of a few microvolts per volt or less, depending on the voltage level and frequency.
