“…where both (4) and (5) proved to be highly accurate [1,18] and precisely correctable for virtually any usable product of f t a [18,22]. It is worth noting that IADC resolution increases with an increasing aperture time, as the IADC has more time to integrate the input voltage and hence achieve higher resolving resolution.…”

This paper reports on an evaluation of the Fluke 8588A digital multimeter (DMM) sampling performance and comparison to Keysight 3458A DMM sampling performance. The design of 8588A type DMM shows both similarities and striking differences in design compared to 3458A type DMM. Apart from their specified sampling capabilities, measurements were performed to evaluate frequency response, noise performance, including a 1 / f type noise and a timing jitter induced noise, as well as phase measurement performance.

“…One approach to investigate the integral linearity of a generator is to measure the SWG output using a digitizer with known linearity, where the total rms value or only the amplitude of the first harmonic is evaluated. For the evaluation of the first harmonic amplitude, a digital multimeter (DMM) Agilent 3458A in DCV sampling mode [15] was used. (In the 10 V range, the 3458A matches the full scale output of the SWG).…”

At the Czech Metrology Institute (CMI) we have developed a precision modular sinewave generator for impedance ratio bridges. The generator was developed to improve previously available designs regarding amplitude and phase accuracy, linearity, absolute stability, stability of the ratio between two outputs and harmonic distortion. It generates up to 7 Vrms in a frequency range from 1 mHz up to 20 kHz, extendable to 100 kHz with small changes to the filters. The amplitude resolution is better than 0.01 μV V−1 of full scale with an output voltage stability of 0.05 μV V−1/30 min and a stability for the ratio between two outputs of 0.02 × 10−6 over several hours. The generator can be powered from internal batteries and is controlled via optically isolated connections. The internal clock and voltage references can be replaced by external ones, optically coupled in the case of the clock. In this paper, we discuss experimental results obtained with the generator used as a signal source in digital impedance bridges with relative combined uncertainties from 10–5 down to 10–8. The generators have been used in a bridge to drive a quantum Hall resistor in the AC regime. The use of a generator with an AC quantum voltmeter will also be discussed. The generator is not only applicable in the field of AC impedance metrology but also for on-site comparisons of AC quantum voltage standards or, in general, where there is a need for precision voltage sources.

“…High-performance digitizers in common use in electrical metrology include the National Instruments NI5922 and the Keysight 3458A (for a thorough review see [11]). These digitizers are used in this work and have previously been the subject of several investigations using TVCs.…”

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.
