CONDUCTED EMISSIONS TEST
3.1 Conducted Power Line Emission Limit
For unintentional device, according to § 15.107(a) Line Conducted Emission Limits is as following
* Decreasing linearly with the logarithm of the frequency
For intentional device, according to §15.207(a) Line Conducted Emission Limit is same as above table.
3.2 Test Setup
3.3 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 0.1 meters is used and is placed
on the ground plane as per ANSI C63.10.
2, Support equipment, if needed, was placed as per ANSI C63.10.
3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.
4, If a EUT received DC power from the USB Port of Notebook PC, the PC’s 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.
3.4 Test Result
PASS
All the test modes completed for test. only the worst result of 8DPSK High Channel was reported
as below:

4 RADIATED EMISSION TEST
4.1 Radiation Limit
For unintentional device, according to § 15.109(a), except for Class A digital devices, the field strength of
radiated emissions from unintentional radiators at a distance of 3 meters shall not exceed the following
values:
For intentional device, according to § 15.209(a), the general requirement of field strength of radiated
emissions from intentional radiators at a distance of 3 meters shall not exceed the above table.
4.2 Test Setup
(1)Radiated Emission Test-Up Frequency Below 30MHz
(2)Radiated Emission Test-Up Frequency 30MHz~1GHz
Page 13 of 29
Report No.: HK1812141952-E
(3)Radiated Emission Test-Up Frequency Above 1GHz
4.3 Test Procedure
1. Below 1GHz measurement the EUT is placed on turntable which is 0.8m above ground plane.
And above 1GHz measurement EUT was placed on low permittivity and low tangent turn table
which is 1.5m above ground plane.
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 varied from 1m to 4m to find out the highest
emissions.
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 test frequency range from 9KHz to 25GHz per FCC PART 15.33(a).
Note:
For battery operated equipment, the equipment tests shall be performed using a new battery.
4.4 Test Result
PASS
All the test modes completed for test. only the worst result of 8DPSK Low Channel was reported
as below:
Page 14 of 29
Report No.: HK1812141952-E
Below 1GHz Test Results:
Antenna polarity: H
Remark: Transd = Cable lose + Antenna factor - Pre-amplifier; Margin = Limit – Level

Report No.: HK1812141952-E
Antenna polarity: V
Remark: Transd = Cable lose + Antenna factor - Pre-amplifier; Margin = Limit – Level
Remark:
(1) Measuring frequencies from 9 KHz to the 1 GHz, Radiated emission test from 9KHz to 30MHz was verified,
and no any emission was found except system noise floor.
(2) * denotes emission frequency which appearing within the Restricted Bands specified in
provision of 15.205, then the general radiated emission limits in 15.209 apply.
(3) The IF bandwidth of EMI Test Receiver between 30MHz to 1GHz was 120KHz, 1 MHz
for measuring above 1 GHz, below 30MHz was 10KHz.

Remark:
(1) Measuring frequencies from 1 GHz to the 25 GHz。
(2) “F” denotes fundamental frequency; “H” denotes spurious frequency. “E” denotes band edge
frequency.
(3) * denotes emission frequency which appearing within the Restricted Bands specified in provision of
15.205, then the general radiated emission limits in 15.209 apply.
(4) Data of measurement within this frequency range shown “--- ” in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small to
be measured.
(5) The IF bandwidth of EMI Test Receiver between 30MHz to 1GHz was 120KHz, 1 MHz for measuring
above 1 GHz, below 30MHz was 10KHz. The resolution bandwidth of test receiver/spectrum analyzer is
1MHz and video bandwidth is 3MHz for peak measurement with peak detector at frequency above 1GHz.
The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video bandwidth is 10Hz for
Average measurement with peak
detection at frequency above 1GHz.
(6) When the test results of Peak Detected below the limits of Average Detected, the Average Detected is
not need completed. For example: Top Channel at Fundamental 73.16dBuV/m(PK Value) <93.98(AV
Limit), at harmonic 53.20 dBuV/m(PK Value) <54 dBuV/m(AV Limit), the Average Detected not need to
completed.
(7)All modes of operation were investigated and the worst-case emissions are reported.

5 BAND EDGE
5.1 Limits
FCC PART 15.249(d) Emissions radiated outside of the specified frequency bands, except for harmonics,
shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission
limits in §15.209, whichever is the lesser attenuation.
5.2 Test Procedure
The band edge compliance of RF radiated emission should be measured by following the guidance
in ANSI C63.10 with respect to maximizing the emission by rotating the EUT, measuring the emission
while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna
height and polarization etc. Set RBW to 100KHz and VBM to 300KHz to measure the peak field strength
and set RBW to 1MHz and VBW to 10Hz to measure the average radiated field strength.The conducted
RF band edge was measured by using a spectrum analyzer. Set span wide enough to capture
the highest in-band emission and the emission at the band edge. Set RBW to 100 KHz and VBW to
300 KHz, to measure the conducted peak band edge.
5.3 Test Result
PASS
All the test modes completed for test. The worst case of Band Edge is GFSK; the test data of
this mode was reported.
