measurement without frequency jittering. The limits shown on the diagrams are EN55022
CLASS B, which is the most common rule for video domestic equipment, such as a set-top
box. As visible on the diagram there is a good margin of the measures with respect to the
QP limits but the measurement exceeds the average measurement limit.

reduction of noise peak obtained using the FMOD pin function is clearly visible. Just by
adding a resistor and a capacitor, a 400 Hz modulating frequency and ±5 kHz of switching
frequency variation is applied. The conducted noise has been measured in all conditions at
different mains voltages on both mains wires with similar results.
