“…A visual comparison of the agreement between the points and the ellipse offers qualitative support for the model of a gain error and an exponential settling time. The plot does not support a model dominated by hysteresis, as has been proposed elsewhere [12]. Hysteresis would result in a rectangular rather than an elliptical figure and our data show no evidence of this.…”

“…In contrast to previous work [12], employing a triangular waveform, the piecewise sinusoid used here has the advantage that the discrete Fourier transform (DFT) can be readily interpreted to extract gain error and settling time and exclude differential nonlinearity (DNL), the deviation between two analogue values corresponding to adjacent digital values .…”

“…The use of multiple ADCs working in parallel with the same master clock may allow noise reduction even further, as the use of numerical signal processing to improve accuracy. It is envisaged to conduct detailed ADCcharacterization with low-distortion waveforms (singletone and multi-tone) in order examine the characterizations against the PTB Josephson waveform synthesizer JWS [6]- [8]. Further developments and detailed measurement results will be presented at the conference.…”

“…For example, the PJVS is used to generate an accurate quantum dc voltage for measuring the induced voltage of a coil that is moving at a constant velocity in the dynamic phase measurement of the watt balance [4][5][6][7][8]. Moreover, it is also used to synthesize stepwise-approximated waveforms [3] in quantum power standard calibration [9], dynamic behavior characterization of analog to digital converters (ADCs) [10], fast-reversed dc comparison [11,12], and high-accuracy ac-dc difference measurement [13,14].…”
