Josephson Voltage Standard

supraVOLTcontrol is a fully automatic
10 V Josephson Voltage Standard System which was developed more than 10 years ago in the Leibniz-Institute of Photonic Technology and since than refined and optimised by Supracon.

The system can facilitate several calibration and measuring modes for dc voltages:

• Calibration of secondary voltage standards
• Calibration of linearity and accuracy of voltmeters (dc) in the voltage range of 0 to ±10 V
• extremely accurate output of arbitrary reference voltages up to 10 V
• direct comparison between two voltage standard systems

No other device combines these functionalities with the highest precision.

supraVOLTcontrol is available in two versions. The first uses liquid helium as a coolant to bring the Josephson Voltage Standard chip to its operating temperature. In the second version the chip is mounted on a coldhead of a pulse tube cooler which requires electrical power only.
