- Abstract:
- In the paper we examine if and how, in a generic measure performed by using a generic PC-based measurement instrument, the measurement uncertainty is influenced by the electromagnetic disturbances. With this aim, by means of experimental tests, we check how the electromagnetic threats affect the single uncertainty sources. In order to apply standard requirements and criteria, we consider the IEC-61326 standard and follow the test procedures prescribed by the IEC-61000-4 series standards. The results show that, in many cases, both radiated and conducted emissions boost the uncertainty sources and, consequently, increase the uncertainty values, worsening the measurement quality.
