8. Concepts of uncertainty in the context of an EMC test
There are many uncertainties in EMC. Like any science that deals with systemic aspects, there are many parameters involved in a measurement, and calculating uncertainties quickly becomes difficult. Calculations that only address uncertainties in the measurement chain provide only a very limited and not the most influential part of the uncertainties in an EMC test. We will verify this in the case of the conducted emissions test discussed earlier.
Let's look at this using the previous system of equations:
