4.1. Block diagram of test setup




4.2. Limits
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.

4.3. Test Procedure
(1) Connect EUT’s antenna output to spectrum analyzer by RF cable.
(2) The bandwidth of the fundamental frequency was measured by spectrum analyzer with 100
    Hz RBW and 300 Hz VBW. The 20dB bandwidth is defined as the total spectrum the power
    of which is higher than peak power minus 20dB.

Note: (1) The emission limits shown in the above table are based on measurements employing a
CISPR QP detector except for the frequency bands 9-90kHz, 110-490kHz and above 1000MHz.
Radiated emissions limits in these three bands are based on measurements employing an
average detector.
(2) At frequencies below 30MHz, measurement may be performed at a distance closer than that
specified, and the limit at closer measurement distance can be extrapolated by below formula:
    Limit3m(dBuV/m)= Limit300m(dBuV/m) + 40Log(300m/3m) = Limit300m(dBuV/m) + 80
    Limit3m(dBuV/m)= Limit30m(dBuV/m) + 40Log(30m/3m) = Limit30m(dBuV/m) + 40


5.3. Test Procedure
(1) EUT was placed on a non-metallic table, 150 cm above the ground plane inside a
semi-anechoic chamber.
(2) Test antenna was located 3m from the EUT on an adjustable mast, and the antenna used as
below table.

               30MHz-1GHz             Trilog Broadband Antenna                   3m

According ANSI C63.10:2013 clause 6.4.4.2 and 6,5.3, for measurements below 30 MHz, the
loop antenna was positioned with its plane vertical from the EUT and rotated about its vertical
axis for maximum response at each azimuth position around the EUT. And the loop antenna also
be positioned with its plane horizontal at the specified distance from the EUT. The center of the
loop is 1 m above the ground. for measurement above 30MHz, the Trilog Broadband Antenna or
Horn Antenna was located 3m from EUT, Measurements were made with the antenna positioned
in both the horizontal and vertical planes of Polarization, and the measurement antenna was
varied from 1 m to 4 m. in height above the reference ground plane to obtain the maximum signal
strength.
(3) Below pre-scan procedure was first performed in order to find prominent frequency spectrum
radiated emissions from 9kHz to 1GHz:
(a) Scanning the peak frequency spectrum with the antenna specified in step (3), and the EUT




                                                                                        Page 13 of 21

was rotated 360 degree, the antenna height was varied from 1m to 4m(Except loop antenna, it’s
fixed 1m above ground.)
(b) Change work frequency or channel of device if practicable.
(c) Change modulation type of device if practicable.
(d) Rotated EUT though three orthogonal axes to determine the attitude of EUT arrangement
produces highest emissions. Spectrum frequency from 9kHz to 1GHz (tenth harmonic of
fundamental frequency) was investigated.
(4) For final emissions measurements at each frequency of interest, the EUT was 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.
(5) The emissions from 9kHz to 1GHz were measured based on CISPR QP detector except for
the frequency bands 9-90kHz, 110-490kHz, for emissions from 9kHz-90kHz,110kHz-490kHz and
above 1GHz were measured based on average detector, for emissions above 1GHz, peak
emissions also be measured and need comply with Peak limit.
(6) The emissions from 9kHz to 1GHz, QP or average values were measured with EMI receiver
with below RBW.

Note 1: * Decreasing linearly with logarithm of frequency.
Note 2: The lower limit shall apply at the transition frequencies.

6.3. Test Procedure
The EUT and Support equipment, if needed, were put placed on a non-metallic table, 80cm
above the ground plane.

Configuration EUT to simulate typical usage as described in clause 2.4 and test equipment as
described in clause 10.2 of this report.

All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.

All support equipment power received from a second LISN.

Emissions were measured on each current carrying line of the EUT using an EMI Test Receiver
connected to the LISN powering the EUT.

The Receiver scanned from 150 kHz to 30MHz for emissions in each of the test modes.

During the above scans, the emissions were maximized by cable manipulation.

The test mode(s) described in clause 2.4 were scanned during the preliminary test.

After the preliminary scan, we found the test mode producing the highest emission level.




                                                                                      Page 17 of 21


Dongguan Dongdian Testing Service Co., Ltd                    Report No.: DDT-R19060302-1E3



The EUT configuration and worse cable configuration of the above highest emission levels were
recorded for reference of the final test.

EUT and support equipment were set up on the test bench as per the configuration with highest
emission level in the preliminary test.

A scan was taken on both power lines, Neutral and Line, recording at least the six highest
emissions.

Emission frequency and amplitude were recorded into a computer in which correction factors
were used to calculate the emission level and compare reading to the applicable limit.

The test data of the worst-case condition(s) was recorded.

The bandwidth of test receiver is set at 9 kHz.


6.4. Test Result
PASS. (See below detailed test result)

Note1: All emissions not reported below are too low against the prescribed limits.
Note2: “-----” means Peak detection; “-----” means Average detection.
Note3: Pre-test AC conducted emission at both voltage AC 120V/60Hz and AC 240V/60Hz,
recorded worse case.

7    Antenna Requirements
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. 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.
