8.4 Test Procedure

1. The EUT is placed on a turntable, which is 0.8m above ground plane for below 1GHz
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 Z position. So the data shown was the Z position only.

8.5 Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Factor, and
subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows:

Corr. Ampl. = Indicated Reading + Antenna Factor + Cable Factor - Amplifier Gain

The “Margin” column of the following data tables indicates the degree of compliance with the
applicable limit. For example, a margin of -7dB means the emission is 7dB below the maximum limit
for Class B. The equation for margin calculation is as follows:
Margin = Corr. Ampl. – Limit
