Nist Demonstrates Remote Operation Of 10 V Josephson Voltage Standard System - National Institute of Standards and Technology - Brief Article

Journal of Research of the National Institute of Standards and Technology, July-August, 2001

A NIST scientist recently demonstrated the new Windows version of the control software for the 10 V Josephson Voltage Standard (JVS) system. This software is the first to provide remote operating capability of JVS systems. A laptop computer with a modem connection in a conference room in Gaithersburg was used to dial-up the 10 V JVS in the Josephson Array Technology Lab in Boulder.

Complete remote control of the system was demonstrated by performing a number of calibrations. The new software will replace older DOS-based software, making the system compatible with current computer hardware and software. Remote operation will reduce operating costs of JVS systems by allowing an operator or repair expert to monitor, control, and diagnose JYS systems from any location. Future enhancements will allows JVS operators to collect statistics and perform all the capabilities of the earlier DOS-based software.
