Abstract
This article presents a 2-V programmable Josephson voltage standard (PJVS) with dual microwave frequency inputs and multiple output taps. The design provides three main features: 1) output voltages with nanovolt resolution; 2) the ability to perform a microwave frequency self-check based on a null voltage measurement; and 3) additional voltage output taps providing simultaneous 10:1 (or 5:1) divided voltage reference for resistive divider calibration. With low heat dissipation, this device is well suited for implementation with a compact cryocooler as a turnkey traveling system.Citation
