3. POWER LINE CONDUCTED EMISSION TEST
According to Paragraph (c) of FCC Part 15 section 15.231, Tests to demonstrate compliance with
the conducted limits are not required for devices which only employ battery power for operation
and which do not operate from the AC power lines or contain provisions for operation while
connected to the AC power lines.

4.3.Radiated Emission Limit
All emanations from a Class B computing devices or system, including any network of
conductors and apparatus connected thereto, shall not exceed the level of field strengths
specified below:
Fundamental Field Strength of Field Strength of Spurious
Frequency(MHz) Fundamental emissions
922.5 QP:81.94dBuV/m at 3m AV:61.94dBuV/m at 3m
distance distance (Above 1GHz)
PK:81.94dBuV/m at 3m
distance (Above 1GHz)
QP:61.94dBuV/m at 3m
distance (Below 1GHz)
Note: The spurious emissions appearing within the frequency band listed in 15.205
Shall also comply with limits shown in section 15.209
4.4.EUT Configuration on Test
The following equipment are installed on Radiated Emission Test to meet the
commission requirements and operating regulations in a manner which tends to
maximize its emission characteristics in normal application.
4.5.Operating Condition of EUT
4.5.1.Setup the EUT and simulator as shown as Section 4.2.
4.5.2.Turn on the power of all equipments.
4.5.3.Let EUT work in Tx mode.
4.6.Test Procedure
The EUT and its simulators are placed on a turn table, which is 0.8 meter high above
ground. The turn table can rotate 360 degrees to determine the position of the maximum
emission level. The EUT is set 3 meters away from the receiving antenna, which is
mounted on a antenna tower. The antenna can be moved up and down between 1 meter
and 4 meters to find out the maximum emission level. Broadband antenna (calibrated
bilog antenna) is used as receiving antenna. Both horizontal and vertical polarization of
the antenna is set on Test. In order to find the maximum emission levels, all of the
interface cables must be manipulated according to ANSI C63.10-2013 on radiated
emission Test.
During the pretest the EUT was rotated through three orthogonal axes to determine the
attitude that maximizes the emissions.
After that the EUT was manually handled to find the orientation that has the maximum
emission, which is the orientation show in the test setup photos.
The bandwidth of the EMI test receiver (R&S ESR7) is set at 120kHz for frequency
range from 30MHz to 1000MHz.
The bandwidth of the Spectrum’s RBW is set at 1MHz and VBW is set at 3MHz for
peak emissions measurement above 1GHz
4.7.Radiated Emission Test Results
PASS.

8. ANTENNA REQUIREMENT

RESULT : PASS

Test Date : Feb.12~Apr.15,2019

Test standard : FCC Part 15.231

Limit : the use of antennas with directional gains that do not exceed 6 dBi

According to the manufacturer declared, the EUT has an Wire antenna, the directional gain
of antenna is -3dBi, and the antenna connector is designed with permanent attachment and no
consideration of replacement. Therefore the EUT is considered sufficient to comply the provision.

9. RADIO FRREQUENCY EXPOSURE COMPLIANCE

RESULT : PASS

Test standard : FCC KDB Publication 447498 D01 V06

Since maximum peak output power of the transmitter is<16mW, i.e.0.000007432780mW<16mW,
hence the EUT is excluded from SAR evaluation according to FCC KDB Publication 447498 D01:
General RF Exposure Guidance V06.
