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.

TEST RESULTS

Not applicable to this device, which is powered by battery.

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)

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. For below 1GHz testing recorded worst at BLE low channel.
2. 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.

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.

Test Results

Remark: The measurement frequency range is from 30MHz to the 10th harmonic of the fundamental
frequency. The lowest, middle and highest channels are tested to verify the spurious emissions and
bandage measurement data.

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. The use of a permanently attached antenna or of an
antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit
so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or
electrical connector is prohibited

FCC CFR Title 47 Part 15 Subpart C Section 15.247(c) (1) (I):

(i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point
operations may employ transmitting antennas with directional gain greater than 6dBi provided the
maximum conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that the
directional gain of the antenna exceeds 6dBi.

Test Result:
The maximum gain of antenna was 0dBi.
