DIN EN 50561-1 VDE 0878-561-1:2014-08

EN 50561-1:2013 specifies limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that uses the low voltage power installation as the transmission medium. The standard applies to equipment that transmits in the frequency range 1,7 MHz to 30 MHz. Procedures are given for the measurement of conducted and radiated disturbances generated by the equipment and limits are specified for the frequency range 9 kHz to 400 GHz. To avoid interference of other services by conducted unsymmetrical disturbances from communication terminals that are connected to low voltage power lines methods of dynamic power control of the transmission level and notching are specified. No measurements need to be performed at frequencies where no limits are specified.
