Conclusion

In conclusion, we will attempt to relate the content of this article to a few rules of EMC metrology. To do this, let's take the example of the evaluation of broad-spectrum emission detected near an electronic device in operation. The measurements prescribed by standardized methods involve collecting the radiated electric field at a distance from this source that can vary from 10 to 3 meters, and in a frequency range from 100 MHz to 1 GHz. Typically, the measurement is performed with a spectrum analyzer connected to a log periodic receiving antenna. The antenna collects the voltage V _L linked to the electric field E _d by the formula E _d = A _F V _L introduced in...
