The SRI 6000 Series Programmable Josephson Voltage Standard (PJVS) is a quantum-based voltage standard that generates highly accurate DC voltages. It uses the Josephson effect to produce voltages with a precision of 1 part in 10^10, making it suitable as a primary voltage standard. The PJVS can also serve as a stable, programmable source for various precision measurements, metrology experiments, and calibrations. It can be used to calibrate Zener references and digital voltage meters, and to generate stepwise-approximated waveforms or sine waves with a rise time of less than 2 microseconds. The PJVS can be used to calibrate commercial voltage calibration sources at frequencies up to a few hundred hertz with a typical measurement uncertainty of 1 part in 10^7, depending on the phase and amplitude stability of the source.
