“…The PJVS systems used in this work are described in more detail in [9,32,33]. PJVS systems use a Josephson Junction array which utilize a microwave source (operating at around 20 GHz or 70 GHz) in conjunction with a bias source to generate a step-wise waveform.…”

“…The static gain stability of two types of integrating digitizer was measured. Firstly, the static gain stability of the 1 V range of a 28 bit integrating digitizer (Keysight 3458A) was investigated using a 1 V PJVS system described in [21,22]. The static gain was measured a few times per day for several days during each operation of the system.…”

“…This observation was repeated at different times over more than two years. Custom developed software evaluates the quantum state (if the PJVS is within its operating margins) of the measurements as described in [21,22]. Rapid and automatic switching ability of the PJVS between quantum voltages helps the gain measurements to be free from thermal noise and offset errors as proved in [22].…”

“…There has been significant interest in the use of JVSs to characterize the performance of digitizers, particularly for use in power measurements. Examples include the use of a PJVS to characterize the NI5922 digitizer [17], the 3458A [18][19][20][21][22] and the Fluke 8558A [23]. A Primary AC Power Standard based on a PJVS has been developed [24] and an ac power standard comparison with PJVS and JAWS has been undertaken [25].…”

A method for traceability to SI for ac voltage and current based on high performance digitizers is presented. In contrast to the existing thermal-based methods, the proposed method utilizes direct traceability to quantum-based waveforms via the use of Josephson voltage systems. This allows not only a simplification of the traceability chain and reduced measurement times but also offers the potential for analysis of the ac voltage and current waveform spectral content, a feature which is not possible using thermal methods. Scaling of current and voltage is achieved by the use of current shunts and resistive voltage dividers respectively. Target operating ranges are up to 1 A and 100 V with a frequency range up to 1 kHz for both. The corresponding target uncertainty for this traceability route is 1 μVV-1 and 2 μAA-1 up to frequencies of 1 kHz. The traceability chain is described and various components are characterized to validate their suitability for this task. It is demonstrated that these uncertainty targets can be met under certain conditions. The use of multi-tone calibration waveforms is investigated to further reduce measurement time. An uncertainty analysis method based on simulation using real component performance data is demonstrated.

The development of a new traceability stepup chain using digital instruments (digitisers) with direct traceability to SI would allow dynamic measurements of current and voltage waveforms. CEM has studied the feasibility of a digital counterpart for the traditional thermal-converter-based step up, which is limited to provide the RMS values of monotone signals. This paper describes and validates this new digital method, obtaining a complete set of calibrations shunt-digitizer for currents up to 1 A. The performed measurements show very promising results, comparable to the well-established thermal-converter approach results, with differences between both techniques lower than 2 μA/A up to 1 kHz.
