2. SYSTEM TEST CONFIGURATION
The tests documented in this report were performed in accordance with ANSI C63.4-2003 and
FCC CFR 47 Part 15 Subpart C.

2.1 EUT Configuration

The EUT configuration for testing is installed on RF field strength measurement to meet the
Commissions requirement and operating in a manner that intends to maximize its emission
characteristics in a continuous normal application.

2.2 EUT Exercise

The calibrated antennas used to sample the radiated field strength are mounted on a non-
conductive, motorized antenna mast 3 or 10 meters from the leading edge of the turntable.

2.3 General Test Procedures

Conducted Emissions The EUT is placed on the turntable, which is 0.8 m above ground plane.
According to the requirements in Section 7.1 of ANSI C63.4-2003.Conducted emissions from
the EUT measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-
Peak detector mode.

Radiated Emissions The EUT is a placed on as turntable, which is 0.8 m above ground plane.
The turntable shall rotate 360 degrees to determine the position of maximum emission level.
EUT is set 3m away from the receiving antenna, which varied from 1m to 4m to find out the
highest emission. And also, each emission was to be maximized by changing the polarization of
receiving antenna both horizontal and vertical. In order to find out the maximum emissions,
exploratory radiated emission measurements were made according to the requirements in
Section 13.1.4.1 of ANSI C63.4-2003.

4.4 Test Equipment List and Details

See section 2.4 of this report.

4.5 Test Procedure

1. Configure the EUT according to ANSI C63.4.

2. The EUT has to be placed 0.4 meter far from the conducting wall of the shielding room and
at least 80 centimeters from any other grounded conducting surface.

3. Connect EUT to the power mains through a line impedance stabilization network (LISN)

4. All the support units are connected to the other LISN. The LISN should provide
50uH/50ohms coupling impedance.

5. The frequency range from 150 KHz to 30 MHz was searched.

6. Use the Channel & Power Controlling software to make the EUT working on selected
channel and expected output power, then use the “H” Patter Generator software to make the
supporting equipments stay on working condition.

7. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with
Maximum Hold Mode.

8. The measurement has to be done between each power line and ground at the power
terminal for each RF channel. Only one RF channel has to be investigated since this test is
independent with the RF channel selection.

4.6 Test Result

Detailed information please refers to the following page.

According to the data in this section, the EUT complied with the FCC 15.107 Conducted margin
for a Class B device, with the worst margin reading of:

highest radiation.
2. The EUT was set 3 meters away from the interference-receiving antenna, which was
mounted on the top of a variable-height antenna tower.
3. The antenna is a broadband antenna, and its height is varied from one meter to four meters
above the ground to determine the maximum value of the field strength. Both horizontal and
vertical polarizations of the antenna are set to make the measurement.
4. For each suspected emission, the EUT was arranged to its worst case and then the antenna
was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0
degrees to 360 degrees to find the maximum reading.

5. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with
Maximum Hold Mode.
6. If the emission level of the EUT in peak mode was 10 dB lower than the limit specified, then
testing could be stopped and the peak values of the EUT would be reported. Otherwise the
emissions that did not have 10 dB margin would be re-tested one by one using the quasi-peak
method or average method as specified and then reported in Data sheet peak mode and QP
mode.

NOTE:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz
for Quasi-peak detection at frequency below 1GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and video bandwidth is
3MHz for Peak detection at frequency above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video
bandwidth is 10Hz for Average detection (AV) at frequency above 1GHz.
