Note: Outputs lines decoupled with ferrite cores allow compliance
with class B for radiated emissions.
All conducted emissions (fig. 23) have been tested according
to IEC/EN 55022 (similar to EN 55011, much better values
than requested by EN 50121-3-2, table 3.1). The limits in fig.
23 apply to quasipeak values, which are always lower then
peak values.
In addition, the values for average must keep a limit 10 dBµV
below the limits in fig. 23 (not shown).

Radiated emissions have been tested according to IEC/EN
55011 (similar to EN 55022), as requested in EN 50121-3-2,
table 6.1. The test is executed with horizontal and vertical
polarization. The worse result is shown in fig. 24.
