Anomalie fonctionnelle; IC's malfunction

Functional anomaly refers to the observation of the active electronic components of a device undergoing an immunity test. The functional anomaly is directly related to the perception of exotic (or strange) behavior of the circuit disturbed by interference induced during an immunity test. In general, the anomaly is the result of non-linear effects restored at the output of the active component by the appearance of DC voltages or demodulation phenomena.

Bande fréquentielle de référence; Normalized frequency bandwidth

The reference frequency band is intended for emission measurements from sources composed of very dense spectral lines degenerating from harmonics of the fundamental frequency of 50 Hz. The reference frequency band normalizes any measurement of this type of spectrum...
