Test method and limit The measurement is made according to ANSI C63.10 and RSS-Gen as follows: The measurement distance is 3m with a shielded loop antenna The Limit has been adjusted with the distance correction factor according to 15.31(f)(2) (+40 dB for 30 m distance and +80 dB for 300 m distance) The measurement is divided into the Preliminary Measurement and the Final Measurement. The suspected frequencies are searched for in Preliminary Measurement with measuring antenna at fixed height using 2-axis EUT position system, set on the turntable, which is rotated 360 degrees. The emissions less than 20 dB below the permissible value are reported. The measurement results are obtained as described: E [µV/m] = URX + ACF Where URX is receiver reading and ACF is total correction factor including cable loss, antenna factor and preamplifier gain (ACF = LCABLES + AF - GPREAMP).

Test method and limit The measurement is made according to ANSI C63.10 and RSS-Gen as follows: The Preliminary Measurement and the Final Measurement is performed in 3 m distance by rotating the turntable of 360 degrees and moving the antenna height between 1-4 m. The Preliminary Measurement is performed with floor absorbers on the floor and measuring antenna at fixed height using 2-axis EUT position system. The Final Measurement is performed without floor absorbers, if the Preliminary Measurement results are closer than 20 dB to the permissible limit. The measurement is divided into the Preliminary Measurement and the Final Measurement. The EUT is placed on a nonconductive plate in the center of the turntable. The emissions less than 20 dB below the permissible value are reported. The measurement results are obtained as described below: E [µV/m] = URX + ACF Where URX is receiver reading and ACF is total correction factor including cable loss, antenna factor and preamplifier gain (ACF = LCABLES + AF - GPREAMP).
