Abstract

In this work we use the Josephson arbitrary waveform synthesizer to provide traceability for the phase of the harmonics of a distorted waveform, relative to its fundamental. For distorted waveforms with rms values in the range from 0.154 V to 0.2 V and harmonic magnitudes from 5% to 40 % of the fundamental, our system can generate odd harmonics up to the 39th with phase uncertainties from 0.002 to 0.010 (k=2.0), depending on the harmonic number and harmonic magnitude.
