31 / 56 page  AN2744 Board description 31/56 5.2 Conducted disturbances 5.2.1 Conducted emissions The EN50065-1 standard describes test setup and procedures for this kind of test. The measures have been done with 220 VAC mains voltage. The test pattern consists of a continuous transmission of a fixed tone at a frequency of 70.8 kHz (72 kHz center frequency minus half the FSK frequency deviation, in this case 2400 Hz) which corresponds to a symbol "1". The output signal measured at the artificial network has a value of 120 dBµV rms, which means a 2 V rms signal on the mains output of the board. The spectrum analyzer performs a peak measure instead of a quasi-peak measure. For continuous sinusoidal signals, the two types of measurement give the same result. Figure 25.
