3.3.Configuration of EUT on Test
The following equipment are installed on Power Line Conducted Emission Test to meet the
commission requirement and operating regulations in a manner which tends to maximize its
emission characteristics in a normal application.
3.4.Operating Condition of EUT
(1) Setup the EUT as shown as Section 3.1.
(2) Turn on the power of all equipment.
(3) Let the EUT work in test mode taking the test.
3.5.Test Procedure
(1) The EUT was placed on a non-metallic table, 80cm above the ground plane. The EUT
Power connected to the power mains through a line impedance stabilization network
(L.I.S.N. 1#). This provided a 50-ohm coupling impedance for the EUT (Please refer to
the block diagram of the test setup and photographs). The other peripheral devices power
cord connected to the power mains through a line impedance stabilization network
(L.I.S.N.#2). Both sides of power line were checked for maximum conducted
interference. In order to find the maximum emission, the relative positions of equipments
and all of the interface cables were changed according to ANSI C63.10:2013 on
conducted Emission test.
(2) The frequency range from 150kHz to 30MHz is checked, the bandwidth of test receiver
(R&S TEST RECEIVER ESCI) is set at 9kHz.
(3) The frequency range from 30MHz to 1000MHz was pre-scanned with a Peak detector
and all final readings of measurement from Test Receiver are Quasi-Peak and Average
values.
(4) The test results are reported on Section 3.6.

4. For frequencies above 1000 MHz, the field strength limits are based on average
limits. However, the peak field strength of any emission shall not exceed the maximum
permitted average limits specified above by more than 20 dB under any condition of
modulation.

4.3.Configuration of EUT on Test
The following equipment are installed on Radiated Emission Test to meet the commission
requirements and operating regulations in a manner that tends to maximize its emission
characteristics in normal application.
4.4.Operating Condition of EUT
(1) Setup the EUT as shown as Section 4.1.
(2) Turn on the power of all equipment.
(3) Let the EUT work in test mode taking the test.
4.5.Test Procedure
(1) The EUT was placed on a non-metallic table, 80 cm above the ground plane inside a
semi-anechoic chamber for below 1GHz and 150 cm above the ground plane inside a
semi-anechoic chamber for above 1GHz. An antenna was located 3m from the EUT on
an adjustable mast. A pre-scan was first performed in order to find prominent radiated
emissions. For final emissions measurements at each frequency of interest, the EUT were
rotated and the antenna height was varied between 1m and 4m in order to maximize the
emission. Measurements in both horizontal and vertical polarities were made and the data
was recorded. In order to find the maximum emission, the relative positions of
equipments and all of the interface cables were changed according to ANSI C63.10: 2013
on Radiated Emission test.
(2) For the radiated emission test above 1GHz:
Place the measurement antenna away from each area of the EUT determined to be a
source of emissions at the specified measurement distance, while keeping the
measurement antenna aimed at the source of emissions at each frequency of significant
emissions, with polarization oriented for maximum response. The measurement antenna
may have to be higher or lower than the EUT, depending on the radiation pattern of the
emission and staying aimed at the emission source for receiving the maximum signal.
The final measurement antenna elevation shall be that which maximizes the emissions.
The measurement antenna elevation for maximum emissions shall be restricted to a range
of heights of from 1 m to 4 m above the ground or reference ground plane.
(3) Test antenna was located 4m from the EUT on an adjustable mast. Below pre-scan

5.2.Test Limit
Please refer section15.249 and section 15.205.
249(d) Emissions radiated outside of the specified frequency bands, except for harmonics, shall
be attenuated by at least 50 dB below the level of the fundamental or to the general radiated
emission limits in section 15.209, whichever is the lesser attenuation.
249(e) As show in section 15.35(b), for frequencies above 1000MHz,the above field strength
limits in paragraphs (a) and (b) of this section are based on average limits. However, the peak
field strength of any emission shall not exceed the maximum permitted average limits specified
above by more than 20 dB under any condition of modulation. For point-to-point operation under

5.3.Configuration of EUT on Test
The following equipment are installed on Radiated Emission Test to meet the commission
requirements and operating regulations in a manner that tends to maximize its emission
characteristics in normal application.
5.4.Operating Condition of EUT
(1) Setup the EUT as shown as Section 5.1.
(2) Turn on the power of all equipment.
(3) Let the EUT work in test mode taking the test.
5.5.Test Procedure
(1) The EUT was placed on a non-metallic table, 150 cm above the ground plane inside a
semi-anechoic chamber. An antenna was located 3m from the EUT on an adjustable
mast. A pre-scan was first performed in order to find prominent radiated emissions. For
final emissions measurements at each frequency of interest, the EUT were rotated and the
antenna height was varied between 1m and 4m in order to maximize the emission.
Measurements in both horizontal and vertical polarities were made and the data was
recorded. In order to find the maximum emission, the relative positions of equipments
and all of the interface cables were changed according to ANSI C63.10: 2013 on
Radiated Emission test.
(2) For the radiated emission test above 1GHz:
Place the measurement antenna away from each area of the EUT determined to be a
source of emissions at the specified measurement distance, while keeping the
measurement antenna aimed at the source of emissions at each frequency of significant
emissions, with polarization oriented for maximum response. The measurement antenna
may have to be higher or lower than the EUT, depending on the radiation pattern of the
emission and staying aimed at the emission source for receiving the maximum signal.
The final measurement antenna elevation shall be that which maximizes the emissions.
The measurement antenna elevation for maximum emissions shall be restricted to a range
of heights of from 1 m to 4 m above the ground or reference ground plane.
(3) Test antenna was located 4m from the EUT on an adjustable mast. Below pre-scan
procedure was first performed in order to find prominent radiated emissions.
(a) Change work frequency or channel of device if practicable.
(b) Change modulation type of device if practicable.
(c) Rotated EUT though three orthogonal axes to determine the attitude of EUT
arrangement produces highest emissions

(5) The frequency range from above 1GHz is checked, the bandwidth of Signal Analyzer
(Signal Analyzer N9020A) is set at 1MHz.
(6) The frequency range from 1GHz to 6GHz was pre-scanned with a peak detector and all
final readings of measurement from Spectrum Analyzer are peak and average values
checked, all measurement distance is 3m in 3m semi anechoic chamber.
(7) Test for all x, y, z axes is performed and only the worst case of X xes was recorded in the
test report.
(8) The test results are reported on Section 5.6.

Please refer section15.249 and section 15.205.
6.3.Test Procedure
(1) The bandwidth is measured at an amplitude level reduced 20dB from the reference level.
The reference level is the level of the highest amplitude signal observed from the
transmitter at the fundamental frequency. Once the reference level is established, the
equipment is conditioned with typical modulating signal to produce the worst-case (i.e.
the widest) bandwidth.
(2) The test receiver RBW set 30KHz,VBW set 100KHz,Sweep time set auto.

7.1.Standard Requirement
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. 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.
7.2.Antenna Connected Construction
The directional gains of antenna used for transmitting is 0dBi, and the antenna is PCB antenna no
consideration of replacement. Please see EUT photo for details.
