TEST CONFIGURATION
TEST PROCEDURE
1.
The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
manual. The EUT is a tabletop system; a wooden table with a height of 0.8 meters is used and is placed on
the ground plane as per ANSI C63.10:2013.
2.
Support equipment, if needed, was placed as per ANSI C63.10:2013.
3.
All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10:2013.
4.
The adapter received AC120V/60Hz power through a Line Impedance Stabilization Network (LISN) which
supplied power source and was grounded to the ground plane.
5.
All support equipments received AC power from a second LISN, if any.
6.
The EUT test program was started. Emissions were measured on each current carrying line of the EUT
using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two
monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1
connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1
connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.
7.
Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
8.
During the above scans, the emissions were maximized by cable manipulation.

3.2. Radiated Emissions and Band Edge
Limit
For intentional device, according to § 15.209(a), the general requirement of field strength of radiated
emission out of authorized band shall not exceed the following table at a 3 meters measurement
distance.
In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also
comply with the radiated emission limits specified in §15.209(a)

(C) Radiated Emission Test Set-Up, Frequency above 1000MHz
Test Procedure
1.
Below 1GHz measurement the EUT is placed on a turntable which is 0.8m above ground plane,
and above 1GHz measurement EUT was placed on a low permittivity and low loss tangent turn
table which is 1.5m above ground plane.
2.
Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating
the turn table from 0° to 360° to acquire the highest emissions from EUT
3.
And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.
4.
Repeat above procedures until all frequency measurements have been completed.
TEST RESULTS
Remark:
1. Radiated emission test from 9 KHz to 10th harmonic of fundamental was verified, and no emission
found except system noise floor in 9 KHz to 30MHz and not recorded in this report.

2. Set the RBW ≥ 3 kHz.
3. Set the VBW ≥ 3× RBW.
4. Set the span to 1.5 times the DTS channel bandwidth.
5. Detector = peak.
6. Sweep time = auto couple.
7. Trace mode = max hold.
8. Allow trace to fully stabilize.
9. Use the peak marker function to determine the maximum power level.
10. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat.
11. The resulting peak PSD level must be 8dBm.

Limit
For digital modulation systems, the minimum 6 dB bandwidth shall be at least 500 kHz
Test Procedure
The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth
of the fundamental frequency was measured by spectrum analyzer with 100 KHz RBW and 300 KHz
VBW. The 6dB bandwidth is defined as the total spectrum the power of which is higher than peak
power minus 6dB.

3.6. Out-of-band Emissions
Limit
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally
modulated intentional radiator is operating, the radio frequency power that is produced by the
intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that
contains the highest level of the desired power, based on either an RF con-ducted or a radiated
measurement, pro-vided the transmitter demonstrates compliance with the peak conducted power
limits. If the transmitter com-plies with the conducted power limits based on the use of RMS averaging
over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under
this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in
§15.209(a) is not required.
Test Procedure
Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum
analyzer to RBW=100 kHz, VBW= 300 kHz, peak detector , and max hold. Measurements utilizing
these setting are made of the in-band reference level, bandedge and out-of-band emissions.

3.7. Antenna Requirement
Standard Applicable
For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be
designed to ensure that no antenna other than that furnished by the responsible party shall be used
with the device.
And according to FCC 47 CFR Section 15.247 (c), if transmitting antennas of directional gain greater
than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the
antenna exceeds 6dBi.
Refer to statement below for compliance
The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a
standard antenna jack or electrical connector is prohibited. Further, this requirement does not apply to
intentional radiators that must be professionally installed.
Antenna Connected Construction
The maximum gain of antenna was 0dBi.
