Abstract
NIST recently reported the first application of a quantum ac Josephson Voltage Standard for calibration of thermal transfer standards in the 1 kHz to 10 kHz frequency range. This paper describes preliminary work on extending its frequency calibration range up to 100 kHz by correcting systematic errors due to voltage leads. A ground loop created by the dc blocks, a previously unaccounted for source of high frequency systematic error, has been identified and its effects partially mitigated.
