“…These sampling voltmeters have a high-resolution integrating ADC (IADC) that operates according to the dual slope principle. The sampling process is such that the sampling instant is not a discrete point in time, but the measured signal is integrated by IADC over the aperture time of AD converter [20][21][22][23][24][25][26][27].…”

Determination of the phase difference between two sinusoidal signals with noise components using samples of these signals is of interest in many measurement systems. The samples of signals are processed by one of many algorithms, such as 7PSF, UQDE and MSAL, to determine the phase difference. The phase difference result must be accompanied with estimation of the measurement uncertainty. The following issues are covered in this paper: the MSAL algorithm background, the ways of treating the bias influence on the phase difference result, comparison of results obtained by applying MSAL and the other mentioned algorithms to the same real signal samples, and evaluation of the uncertainty of the phase difference.

“…S OON after the 3458A DMM was introduced to a market in 1988, metrologists in the National Metrology Institutes (NMI) started using its novel sampling capabilities for various measurements, achieving groundbreaking performance increase, particularly in terms of lowering measurement uncertainties [1,2,3,4,5,6,7] in various measurement areas. This was achieved by using a custom made multi-slope integrating analogue-to-digital converter (IADC), which exhibits a few key properties built in by design.…”

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.
