Electromagnetic Emissions

All conducted emissions (fig. 8) have been tested as per EN 55011, group 1, class A. These limits are much stronger than

requested in EN 50121-3-2:2016, table 2.1, and coincide with EN 50121-4:2016, table 1.1. The values in fig. 8 are quasipeak values,

which are always lower then peak values.

The average values must respect a margin of 10 dBµV below the limits for quasipeak.

Radiated emissions have been tested according to EN 55011, group 1, class A. These limits are similar to the requirements of

EN 50121-3-2:2016 and EN 50121-4:2016, both calling up EN 61000-6-4+A1:2011, table 1. The tests were executed with horizontal

and vertical polarization. The worse result is shown in Fig. 9.

Note: The highest frequency of the internal sources of EUT is less than 108 MHz. Hence, Radiated Measurement was made up to 1 GHz.

Non-accredited measurement up to 6 GHz are available on request.
