Test Setup
1. The EUT and supporting equipment were set up in accordance with the requirements of
Procedure
the standard on top of a 1.5m x 1m x 0.8m high, non-metallic table.
2. The power supply for the EUT was fed through a 50Ω /50mH EUT LISN, connected to
filtered mains.

3. The RF OUT of the EUT LISN was connected to the EMI test receiver via a low-loss
coaxial cable.
4. All other supporting equipment were powered separately from another main supply.
5. The EUT was switched on and allowed to warm up to its normal operating condition.
6. A scan was made on the NEUTRAL line (for AC mains) or Earth line (for DC power)
over the required frequency range using an EMI test receiver.
7. High peaks, relative to the limit line, The EMI test receiver was then tuned to the
selected frequencies and the necessary measurements made with a receiver bandwidth
setting of 10 kHz.
8. Step 7 was then repeated for the LIVE line (for AC mains) or DC line (for DC power).

Test Setup
Procedure
1.
The EUT was switched on and allowed to warm up to its normal operating condition.
2.
The test was carried out at the selected frequency points obtained from the EUT
characterization. Maximization of the emissions, was carried out by rotating the EUT,
changing the antenna polarization, and adjusting the antenna height in the following
manner:
a.
Vertical or horizontal polarization (whichever gave the higher emission level
Test Report
18071115-FCC-E

over a full rotation of the EUT) was chosen.
b.
The EUT was then rotated to the direction that gave the maximum
emission.
c.
Finally, the antenna height was adjusted to the height that gave the maximum
emission.
3.
The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is
120 kHz for Quasiy Peak detection at frequency below 1GHz.
4.
The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 3MHz with Peak detection for Peak measurement at frequency above
1GHz.
The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video
bandwidth with Peak detection for Average Measurement as below at frequency
above 1GHz.
■ 1 kHz (Duty cycle < 98%) □ 10 Hz (Duty cycle > 98%)
5.
Steps 2 and 3 were repeated for the next frequency point, until all selected frequency
points were measured.

Note1: The highest frequency of the EUT is 2462MHz, so the testing has been conformed to 5*2462MHz
=12,310MHz.
Note2: The frequency that above 3GHz is mainly from the environment noise.
Note3: The AV measurement performed, more than 20dB below limit so AV test data was not presented.
