Frequency Uncertainty Analysis for Josephson Voltage Standard
Yi-hua D. Tang, Michael A. Lombardi, David A. Howe
The uncertainty in voltage measurement in a Josephson voltage standard (JVS) is proportional to the uncertainty of frequency measurement. The 10 MHz time-base from various commonly used frequency standards for JVS are analyzed using Allan variance to determine the contribution to the uncertainty budget for voltage measurement. The 75 GHz microwave source along with phase-lock electronics and frequency counter for a Josephson junction array is also analyzed for its stability and contribution to JVS uncertainty budget. The results provide realistic estimation for uncertainty contributions of time base and frequency measurements in JVS.
