*1 Note:
According to standard EN 55014-1: 2006+A1: 2009, this measurement may be made at closer distance, down to 3 m. An inverse proportionality factor of 20 dB per decade shall be used to normalize the measured data to the specified distance for determining compliance.
*2 Note:
According to standard EN 55022: 2006+A1: 2007, if the field-strength measurement at 10 m cannot be made because of high ambient noise levels, or for other reasons, measurement of class B EUTs may be made at closer distance, for example 3 m. An inverse proportionality factor of 20 dB per decade should be used to normalize the measured data to the specified distance for determining compliance.
*3 Note:
According to standard EN 61000-6-3: 2007, radiated disturbance may be measured at 3 m distance using the limits increased by 10 dB.
For standard EN 55015, frequency range for radiated disturbance is lower; for standard EN 61000-6-4, generally the equipment under test is larger, so the distance between antenna and the EUT is 10 m, not 3 m, in order to avoid near field effect.
