Abstract

Accurate characterization of an AC voltage meter is of great significance to reduce the measurement uncertainty of electrical parameters. This paper provides a detailed analysis of three sampling modes of Keysight 3458A which is widely used in electrical laboratories, namely DCV sampling, direct sampling, and sub-sampling. The stability of Keysight 3458A is characterized using AC quantum voltages generated by an AC Josephson voltage standard. The frequency response of Keysight 3458A in DCV sampling mode with different aperture times is characterized. The dynamic characteristics of Keysight 3458A in direct sampling and sub-sampling modes are evaluated by measuring the signal-to-noise ratio, spurious-free dynamic range, total harmonic distortion, and signal-to-distortion ratio. The results expand the application area of AC quantum voltages and lay a foundation for improving the sampling performance of Keysight 3458A.
