The EUT is placed on the turntable, which is 0.8 m above ground plane. According to
the requirements in Section 6.2.1 of ANSI C63.10-2013 Conducted emissions from the
EUT measured in the frequency range between 0.15 MHz and 30MHz using Quasi-peak

Notes:
1. Measuring frequencies from 9k~10th harmonic (ex. 10GHz), No emission found between lowest internal used/generated
frequency to 30 MHz.
2. Radiated emissions measured in frequency range from 9k~10th harmonic (ex. 10GHz) were made with an instrument
using Peak detector mode.

9. BANDEDGES MEASUREMENT

9.1. Standard Applicable
Emissions radiated outside of the specified frequency bands, except for harmonics,
shall be attenuated by at least 50 dB below the level of the fundamental or to the
general radiated emission limits in Section 15.209, whichever is the lesser attenuation.

9.3. Test Procedure
The EUT is placed on a turntable, which is 0.8m above the ground plane. The turntable
shall be rotated for 360 degrees to determine the position of maximum emission level.
EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find
out the highest emission. Set the spectrum analyzer in the following setting in order to
capture the lower and upper band-edges of the emission:
Peak: RBW=120KHz, RBW=300KHz / Sweep=AUTO
Repeat the procedures until the peak versus polarization are measured.
