Abstract
This paper describes a new generation of Josephson Arbitrary Waveform Synthesizers which generate ac waveforms with a root-mean-squared (rms) amplitude of 3 V over a quantum-accurate operating range greater than 1 mA at 1 kHz. This system is composed of two chips with a total of 204 960 Josephson junctions (JJs) co-located at 4.6 K on a cryocooler. To test for systematic errors in the system, we generate a null voltage by shifting the phase of the waveform generated by half the JJs by 180°. The measured residual rms amplitude of 51 NV implies that the two halves of the system can create voltages with an rms magnitude of 1.5 V which match to 3 parts in 1e8.Proceedings Title
