Abstract
This paper describes a dual Josephson impedance bridge capable of comparing any two impedances, that is, with any amplitude ratio and relative phase, over a wide range of frequency. A new, more compact, design has been achieved by mounting the two Josephson Arbitrary Waveform Synthesizers (dual JAWS) side by side in a single cryoprobe. We measure the crosstalk between the two JAWS sources and show that, by interchanging the impedances within the bridge, the effect of the crosstalk between JAWS sources can be reduced to a negligible level.Proceedings Title
