Abstract

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. The given comprehensive report is crucial for careful application of DMMs in metrology tasks with optimal utilization of their performance.
