1.4 Test Methodology
All measurements contained in this report were conducted with ANSI C63.4-2003, American
National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage
Electrical and Electronic Equipment in the range of 9 kHz to 40 GHz.

The equipment under test (EUT) was configured to measure its highest possible radiation level. The
test modes were adapted accordingly in reference to the Operating Instructions.

The maximum emission levels emanating from the device are compared to the FCC Part 15 Subpart
C limits for radiation emissions and the measurement results contained in this test report show that
EUT is to be technically compliant with FCC requirements.

All measurement required was performed at laboratory of Global United Technology Service Co.,
Ltd at 2nd Floor, Block No. 2, Laodong Industrial Zone, Xixiang Road Baoan District, Shenzhen,
China

The test facility is recognized, certified, or accredited by the following organizations:

FCC – Registration No.: 600491
Global United Technology Service Co., Ltd, Shenzhen EMC Laboratory has been registered and
fully described in a report filed with the (FCC) Federal Communications Commission. The
acceptance letter from the FCC is maintained in our files.

The facility also complies with the radiated and AC line conducted test site criteria set forth in ANSI
C63.4-2003.

2 - Test Procedure

GENERAL: This report shall NOT be reproduced except in full without the written approval of
Shenzhen Exact Standard Testing Technology Co., Ltd.. The EUT was transmitting a test signal
during the testing.

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2003 using
a spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a microvolt at the
output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz
up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0GHz. The ambient temperature of
the EUT was 74.3oF with a humidity of 69%.

FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the
meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna
correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in
terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter
Reading.

Example:
Freq (MHz) METER READING + ACF = FS
33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m

ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The EUT was placed on
a table 80 cm high and with dimensions of 1m by 1.5m. The EUT was placed in the center of the
table (1.5m side). The table used for radiated measurements is capable of continuous rotation.
When an emission was found, the table was rotated to produce the maximum signal strength. At
this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the
horizontal and vertical planes.

3 - DISTURBANCE VOLTAGE AT THE MAINS TERMINALS
3.1 Measurement Uncertainty
All measurements involve certain levels of uncertainties, especially in field of EMC. The factors
contributing to uncertainties are spectrum analyzer, cable loss, and LISN.

The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of any
conducted emissions measurement is +2.4 dB.

3.2 Requirements (15.207):

Limits ( dBuV)
Frequency Range (MHz)
Quasi-Peak Average
0.150～0.500 66~56 56~46
0.500～5.000 56 46
5.000～30.00 60 50

Note: (1)The tighter limit shall apply at the edge between two frequency bands.

3.3 EUT Setup
The setup of EUT is according with ANSI C63.4-2003 measurement procedure. The specification
used was the FCC Rules and Regulations Part 15 Subpart C limits.

The EUT was placed center and the back edge of the test table.

The AV cables were draped along the test table and bundled to 30-40cm in the middle.

The spacing between the peripherals was 10 cm.

Maximum emission emitted from EUT was determined by manipulating the EUT, support equipment,
interconnecting cables and varying the mode of operation and the levels in the final result of the test
were recorded with the EUT running in the operating mode that maximum emission was emitted.

3.4 Instrument Setup
The test receiver was set with the following configurations:

Test Receiver Setting:

Frequency Range……………………….150 KHz to 30 MHz
Detector…………………………………..Peak & Quasi-Peak & Average
Sweep Speed……………………………Auto
IF Band Width……………………….…..9 KHz

3.5 Test Procedure
During the conducted emission test, the EUT power cord was connected to the auxiliary outlet of the
first Artificial Mains.

Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance
using all installation combination.

All data was recorded in the peak detection mode. Quasi-peak and Average readings were only
performed when an emission was found to be marginal (within -10 dBµV of specification limits).
Quasi-peak readings are distinguished with a "QP". Average readings are distinguished with a "AV".

3.6 Summary of Test Results
According to the data in section 3.6, the EUT complied with the FCC Part 15 Subpart C Conducted
margin, with the worst margin reading of:
