A pre-compliance test to EN55022 (Class B) European normative has been performed
using an EMC analyzer and an LISN. First of all, a measurement of the background noise
(board disconnected from the mains) was performed and is shown in
Figure 39 .
Then the peak and average EMC measurements at 115 V
AC
/full load and 230 V
AC
/full load
were performed and the results are shown in
Figure 40 , 41 , 42 and 43 .
