8.4 Test Procedure
1. The EUT is placed on a turntable, which is 0.8m above ground plane.
2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission
level.
3. EUT is set 3m away from the receiving antenna, which is moved from 1m to 4m to find out the
maximum emissions. The spectrum was investigated from the lowest radio frequency signal
generated in the device, without going below 9 kHz, up to the tenth harmonic of the highest
fundamental frequency or to 40 GHz, whichever is lower.
4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
5. And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.
6. Repeat above procedures until the measurements for all frequencies are complete.
7. The radiation measurements are tested under 3-axes(X, Y, Z) position(X denotes lying on the
table, Y denotes side stand and Z denotes vertical stand). After pre-test, It was found that the
worse radiation emission was get at the X position. So the data shown was the X position only.
