5.2.1 Conducted
emissions
The EN50065-1 standard describes the test setup and procedures for testing conducted
emissions.
The conducted emissions measurements have been taken with 220 V
ac
mains voltage. The
test pattern consists of a continuous transmission of a “1010” continuous sequence at 2400
baud, deviation 1. The output signal measured at the CISPR artificial network has a value of
120 dBuV
RMS
which means a signal of 2 V
RMS
on the mains output.
