EMI measurements
A pre-compliant test to the EN55022 (class B) European norm has been performed using an
EMC analyzer and a LISN.
First of all, an average measurement of the background noise (board disconnected from the
mains) has been performed and is reported in Figure 46.
Figure 46.
Average measurement of background noise (board disconnected from
mains)
The average EMC measurements at 115 Vac/full load and 230 Vac/full load have then been
performed and the results are shown in Figure 47 and Figure 48 respectively.
