In this paper the setting up of a binary Josephson array waveform system for synthesization of arbitrary waveforms is described. The authors are with the Electricity Laboratory in the Metrology and Calibration Centre of INTA (Instituto Nacional de Tecnica Aeroespacial) in Torrejon de Ardoz, Madrid, Spain.
We present the combination of two Josephson waveform synthesizers to generate waveforms with low harmonic distortion [below$-$110 dBc (carrier)] and amplitudes above the 1-V level. Fast and flexible code programming enables pulse-driven Josephson arrays to synthesize arbitrary waveforms. We have used the pulse-driven system to cancel the harmonic content from the binary array that can reach 1-V amplitudes. The quantum nature of the Josephson synthesizer ensures very stable amplitudes (better than6×10−8) and no frequency drift. This performance, together with the ability to synthesize arbitrary waveforms, can make this synthesizer a relevant tool for characterizing precision electronics and ac voltage metrology.
