| Résumé | The stability of an ac voltage source fabricated at the National Research Council Canada (NRC) is investigated. In this work, differential sampling was used to monitor the source voltage with respect to a step-wise approximated reference waveform generated by the Programmable Josephson Voltage Standard (PJVS) at 4 V and at 1 V. The frequency dependence of the source error is extracted, and the same measurements are repeated 13.5 months later to determine the long-term stability. Different digitizers are used to evaluate input filter effects. The NRC ac voltage source is found to be a suitable travelling standard with a stability of < 4 µV/V per year. At the National Institute of Standards and Technology (NIST), differential sampling was used to monitor the difference between a Josephson Arbitrary Waveform Synthesizer (JAWS) at 1 V and this source. Information is obtained about the effect of relative humidity on the source phase. |
