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. 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.
8. During the above scans, the emissions were maximized by cable manipulation.

TEST RESULTS
Remark: All modes of GFSK, Pi/4 DQPSK, and 8DPSK were test at Low, Middle, and High
channel; only the worst result of 8DPSK High Channel was reported as below:

3.2. Radiated Emissions and Band Edge
Limit
According 15.249, the field strength of emissions from intentional radiators operated within
2400MHz-2483.5 MHz shall not exceed 94dBμV/m (50mV/m):
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.
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)

TEST CONFIGURATION
(A) Radiated Emission Test Set-Up, Frequency Below 30MHz
(B) Radiated Emission Test Set-Up, Frequency below 1000MHz
V1.0 Page 13 of 30 Report No.: CTL1610280303-WF
(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. We measured Radiated Emission at GFSK, π/4 DQPSK and 8DPSK mode from 9 KHz to 25GHz
and recorded worst case at GFSK DH5 mode.
2. For below 1GHz testing recorded worst at GFSK DH5 low channel.
3. 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.

REMARKS:
1. Emission level (dBuV/m) =Raw Value (dBuV)+Correction Factor (dB/m)
2. Correction Factor (dB/m) = Antenna Factor (dB/m)+Cable Factor (dB)-Pre-amplifier Factor
3. Margin value = Limit value- Emission level.
4. -- Mean the PK detector measured value is below average limit.
5. The other emission levels were very low against the limit.
6. RBW1MHz VBW3MHz Peak detector is for PK value; RBW 1MHz VBW10Hz Peak
detector is for AV value.
7. For fundamental frequency, RBW 3MHz VBW 3MHz Peak detector is for PK Value; RMS
detector is for AV value.

ANALYZER
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 30 KHz RBW and 100 KHz
VBW.
The 20dB bandwidth is defined as the total spectrum the power of which is higher than peak power
minus 20dB.

3.4. 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.
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 antenna used in this product is an PCB Antenna, The directional gains of antenna used for
transmitting is 0dBi.
