Bay Area Compliance Laboratories Corp. (Shenzhen)                             Report No.: RSZ190708831-00

FCC§15.203 - ANTENNA REQUIREMENT
Applicable Standard
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 shall be considered sufficient to comply with
the provisions of this section.


Antenna Connector Construction
The EUT has an integral antenna arrangement, which was permanently attached and the antenna gain is
2.5 dBi, fulfill the requirement of this section. Please refer to EUT photos.


Result: Compliant.




FCC Part 15.227                                                                                Page 8 of 14


Bay Area Compliance Laboratories Corp. (Shenzhen)                             Report No.: RSZ190708831-00

FCC§15.205, §15.209, §15.227(a), §15.227 (b) – FIELD STRENGTH AND
RESTRICTED BAND EMISSIONS
Applicable Standard
According to FCC §15.227 (a), the field strength if any emission within this band shall not exceed 10,000
microvolts/meter at 3 meters.

(b) The field strength of any emissions which appear outside of this band shall not exceed the general
radiated emission limits in §15.209.


Measurement Uncertainty
All measurements involve certain levels of uncertainties, especially in field of EMC. The factors
contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna
directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency
interpolation, measurement distance variation, site imperfections, mismatch (average), and system
repeatability.

Based on CISPR 16-4-4, The Treatment of Uncertainty in EMC Measurements, the best estimate of the
uncertainty of a radiation emissions measurement at Bay Area Compliance Laboratories Corp. (Shenzhen)
is 4.0 dB.(k=2, 95% level of confidence), and the uncertainty will not be taken into consideration for all
the test data recorded in the report.


EUT Setup




The radiated emission tests were performed in the 3 meters, using the setup accordance with the ANSI
C63.10-2013. The specification used was the FCC Part 15.205 and 15.209 and 15.227 limits.



FCC Part 15.227                                                                                Page 9 of 14


Bay Area Compliance Laboratories Corp. (Shenzhen)                                Report No.: RSZ190708831-00

EMI Test Receiver Setup
The system was investigated from 9 kHz to 1000 MHz.


Corrected Amplitude & Margin Calculation
The Corrected Amplitude is calculated by adding the Antenna Loss and Cable Loss, and subtracting the
Amplifier Gain from the Meter reading. The basic equation is as follows:

        Corrected Amplitude = Meter Reading + Correction Factor
        Correction Factor = Antenna Loss + Cable Loss - Amplifier Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7dB means the emission is 7dB below the limit. The equation for margin
calculation is as follows:

        Margin = Limit – Corrected Amplitude

FCC§15.215(c) - 20dB EMISSION BANDWIDTH
Applicable Standard
Intentional radiators operating under the alternative provisions to the general emission limits, as contained
in § 15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB
bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section
under which the equipment operates, is contained within the frequency band designated in the rule section
under which the equipment is operated.


Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
   from an external generator.

2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect it to
   measurement instrument. Then set it to any one convenient frequency within its operating range. Set a
   reference level on the measuring instrument equal to the highest peak value.

3. Measure the frequency difference of two frequencies that indicated 20dB bandwidth.

4. Repeat above procedures until all frequencies measured were complete.
