Abstract
We created a Josephson Arbitrary Waveform Synthesizer (JAWS) with a root-mean-square (rms) output magnitude of 2 V. This system is composed of two 1 V chips operating on a cryocooler. By controlling the relative phase of the two chips output voltage, we add the voltages in quadrature and create rms output voltages between (1+1) V=2 V and (1-1) V=0 V. We use this control to compare the two halves of the system as a function of the relative phase, and measure a difference of 8 parts in 10^8 at a nominal rms amplitude of 1 V and 1 kHz.Conference Dates
