2. TEST METHODOLOGY
All measurements contained in this report were conducted with ANSI C63.10: 2013, American
National Standard of Procedures for Compliance Testing of Unlicensed Wireless Devices.
The radiated testing was performed at an antenna-to-EUT distance of 3 meters. All radiated and
conducted emissions measurement was performed at Shenzhen LCS Compliance Testing Laboratory
Ltd.

2.1. EUT Configuration
The EUT configuration for testing is installed on RF field strength measurement to meet the
Commissions requirement and operating in a manner that intends to maximize its emission
characteristics in a continuous normal application.

2.2. EUT Exercise
The EUT was operated in the engineering mode to fix the TX frequency that was for the purpose of
the measurements.
According to its specifications, the EUT must comply with the requirements of the Section 15.203,
15.205, 15.207, 15.209 and 15.249 under the FCC Rules Part 15 Subpart C.

2.3. General Test Procedures

1.1.1.2.3.1 Conducted Emissions

The EUT is directly placed on the ground. According to the requirements in Section 6.2.1 of ANSI
C63.10-2013 Conducted emissions from the EUT measured in the frequency range between 0.15
MHz and 30MHz using Quasi-peak and average detector modes.

1.1.2.2.3.2 Radiated Emissions

The EUT is placed on a turntable, which is directly placed on the ground. The turntable shall rotate
360 degrees to determine the position of maximum emission level. EUT is set 3m away from the
receiving antenna, which varied from 1m to 4m to find out the highest emission. And also, each
emission was to be maximized by changing the polarization of receiving antenna both horizontal and
vertical. In order to find out the maximum emissions, exploratory radiated emission measurements
were made according to the requirements in Section 6.3 of ANSI C63.10-2013

Notes:
1). Measuring frequencies from 9 KHz - 10th harmonic (ex. 26GHz), No emission found between lowest
internal used/generated frequency to 30 MHz.
2). Radiated emissions measured in frequency range from 9 KHz - 10th harmonic (ex. 26GHz) were made
with an instrument using Peak detector mode.

8.4. Test Procedures

Setup:
--- The equipment was set up to simulate a typical usage like described in the user manual or
described by manufacturer.
--- If the EUT is a tabletop system, a table with 0.8 m height is used, which is placed on the ground
plane.
--- If the EUT is a floor standing device, it is placed on the ground plane with insulation between both.
--- Auxiliary equipment and cables were positioned to simulate normal operation conditions
--- The AC power port of the EUT (if available) is connected to a power outlet below the turntable.
--- The measurement distance is 3 meter.
--- The EUT was set into operation.

Premeasurement:
--- The turntable rotates from 0° to 315° using 45° steps.
--- The antenna is polarized vertical and horizontal.
--- The antenna height changes from 1 to 3 meter.
--- At each turntable position, antenna polarization and height the analyzer sweeps three times in
peak to find the maximum of all emissions.

Final measurement:
--- The final measurement will be performed with minimum the six highest peaks.
--- According to the maximum antenna and turntable positions of premeasurement the software
maximize the peaks by changing turntable position (± 45°) and antenna movement between 1 and 4
meter.
--- The final measurement will be done with QP detector with an EMI receiver.
--- The final levels, frequency, measuring time, bandwidth, antenna height, antenna polarization,
turntable angle, correction factor, margin to the limit and limit will be recorded. Also a plot with the
graph of the premeasurement with marked maximum final measurements and the limit will be stored.
