3.4 TEST Methodology & General Test Procedures
All testing as described bellowed were performed in accordance with ANSI C63.4:2014
and ANSI C63.10:2013.
Conducted Emissions
The EUT is placed on a wood table, which is at 0.8 m above ground plane acceding to
clause 15.207 and requirements of ANSI C63.4:2014. Conducted emissions from the EUT
measured in the frequency range between 0.15 MHz and 30MHz are using CISPR
Quasi-Peak / Average detectors.
Radiated Emissions
The EUT is a placed on a turn table, which is 0.8 m above ground plane. The turntable was
rotated through 360 degrees to determine the position of maximum emission level. The
EUT is placed at 3m away from the receiving antenna, which varied from 1m to 4m to find
out the highest emission. Each emission was to be maximized by changing the polarization
of receiving antenna both horizontal and vertical.
1) Putting the EUT on the platform and turning on the EUT (on/off button on the bottom
of the EUT).
2) Setting test channel described as “Channel setting and operating condition”, and
testing channel by channel.
3) For the maximum output power measurement, we followed the method of
measurement KDB558074 D01.
4) For the spurious emission test based on ANSI(2014), at the frequency where below
1GHz used quasi-peak detector mode; where above 1GHz used the peak and
average detector mode. IF the peak value may be under average limit, the average
mode will not be performed.

6. Test of Conducted Emission
6.1 Test Limit
Conducted Emissions were measured from 150 kHz to 30 MHz with a bandwidth of 9 KHz
on the 110 VAC power and return leads of the EUT according to the methods defined in
ANSI C63.4-2014 Section 3.1.
The EUT was placed on a nonmetallic stand in a shielded
room 0.8 meters above the ground plane as shown in section 2.2.
The interface cables
and equipment positioning were varied within limits of reasonable applications to determine
the position produced maximum conducted emissions.

b. Connect EUT to the power mains through a line impedance stabilization network (LISN).
c. All the support units are connecting to the other LISN.
d. The LISN provides 50 ohm coupling impedance for the measuring instrument.
e. The FCC states that a 50 ohm, 50 micro-Henry LISN should be used.
f.
Both sides of AC line were checked for maximum conducted interference.
g. The frequency range from 150 kHz to 30 MHz was searched.
h. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with
Maximum Hold Mode.

7. Test of Radiated Emission
7.1 Test Limit
In any 100kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is
produced by the intentional radiator shall be at least 20dB below that in the 100kHz
bandwidth within the band that contains the highest level of the desired power, based on
either an RF conducted or a radiated measurement. If the transmitter measurement is
based on the maximum conducted output power, the attenuation required under this
paragraph shall be 30dB instead of 20dB. In addition, radiated emissions which fall in
section 15.205(a) the restricted bands must also comply with the radiated emission limit
specified in section 15.209(a).

7.2 Test Procedures
a. The EUT was placed on a rotatable table top 0.8 meter above ground.
b. The EUT was set 3 meters from the interference receiving antenna which was mounted on the
top of a variable height antenna tower.
c. The table was rotated 360 degrees to determine the position of the highest radiation.
d. The antenna is a broadband antenna and its height is varied between one meter and four
meters above ground to find the maximum value of the field strength both horizontal
polarization and vertical polarization of the antenna are set to make the measurement.
e. For each suspected emission the EUT was arranged to its worst case and then tune the
antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the
maximum reading.
f. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function and specified
bandwidth with Maximum Hold Mode.
g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then
testing will be stopped and peak values of EUT will be reported, otherwise, the emissions which
do not have 3 dB margin will be repeated one by one using the quasi-peak method and
reported.
h. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than

average limit (that means the emission level in peak mode also complies with the limit in
average mode), then testing will be stopped and peak values of EUT will be reported, otherwise,
the emissions will be measured in average mode again and reported.
i. “Cone of radiation” has been considered to be 3dB bandwidth of the measurement antenna.

Note:
1.
Emission level = Reading level + Correction factor
2.
Correction factor : Antenna factor, Cable loss, Pre-Amp, etc.
3.
All emissions as described above were determining by rotating the EUT through three
orthogonal axes to maximizing the emissions if the EUT belongs to hand-held or
body-worn devices.
4.
Measurements above 1000 MHz, Peak detector setting:
1 MHz RBW with 1 MHz VBW (Peak Detector).
5.
Measurements above 1000 MHz, Average detector setting:
1 MHz RBW with 10Hz VBW (RMS Detector).
6.
Peak detector measurement data will represent the worst case results.
Where limits are specified for both average and peak detector functions, if the peak
measured
value complies with the average limit, it is unnecessary to perform an average measurement.

10. Carrier Frequency Separation
10.1 Test Limit
a. Frequency hopping systems shall have hopping channel carrier frequencies
separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping
channel, whichever is greater. Alternatively, frequency hopping systems
operating in the 2400-2483.5 MHz band may have hopping channel carrier
frequencies that are separated by 25 kHz or two-thirds of the 20 dB
bandwidth of the hopping channel, whichever is greater, provided the
systems operate with an output power no greater than 125 mW.
10.2 Test Procedures
b. The transmitter output was connected to spectrum analyzer.
c. The spectrum analyzer’s resolution bandwidth were set at 100KHz RBW and
300KHz VBW as that of the fundamental frequency. Set the sweep time=auto
couple.
d. The Carrier Frequency Separation was measured and recorded.
