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 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.

3.3. Occupied Bandwidth Measurement
Limit

N/A

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 3 KHz RBW and 10 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.

Test Result:

The directional gains of antenna used for transmitting is 0 dBi, and the antenna connector is designed
with permanent attachment and no consideration of replacement. Please see EUT photo for details.
