(EUT: Stereo Bluetooth Headphones)
5.2.The Requirement For Section 15.247(a)(1)
Section 15.247(a)(1): 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.
5.3.EUT Configuration on Measurement
The equipment are installed on the emission measurement to meet the commission
requirements and operating regulations in a manner which tends to maximize its emission
characteristics in normal application.
5.4.Operating Condition of EUT
5.4.1.Setup the EUT and simulator as shown as Section 5.1.
5.4.2.Turn on the power of all equipment.
5.4.3.Let the EUT work in TX (Hopping off) modes measure it. The transmit
frequency are 2402-2480MHz. We select 2402MHz, 2441MHz, and 2480MHz
TX frequency to transmit.
5.5.Test Procedure
5.5.1.The transmitter output was connected to the spectrum analyzer through a low
loss cable.
5.5.2.The RBW should be 1%~5% of OBW.
5.5.3.The 20dB bandwidth is defined as the total spectrum the power of which is
higher than peak power minus 20dB.

6.2.The Requirement For Section 15.247(a)(1)
Section 15.247(a)(1): 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. The
system shall hop to channel frequencies that are selected at the system hopping rate from
a pseudo randomly ordered list of hopping frequencies. Each frequency must be used
equally on the average by each transmitter. The system receivers shall have input
bandwidths that match the hopping channel bandwidths of their corresponding
transmitters and shall shift frequencies in synchronization with the transmitted signals.
6.3.EUT Configuration on Measurement
The equipment are installed on the emission measurement to meet the commission
requirements and operating regulations in a manner which tends to maximize its emission
characteristics in normal application.
6.4.Operating Condition of EUT
6.4.1.Setup the EUT and simulator as shown as Section 6.1.
6.4.2.Turn on the power of all equipment.

10.2.The Requirement For Section 15.247(d)
Section 15.247(d): In any 100 kHz 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 20 dB below
that in the 100 kHz bandwidth within the band that contains the highest level of the
desired power, based on either an RF conducted or a radiated measurement, provided the
transmitter demonstrates compliance with the peak conducted power limits. If the
transmitter complies with the conducted power limits based on the use of RMS averaging
over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation
required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the
general limits specified in Section 15.209(a) is not required. In addition, radiated
emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
comply with the radiated emission limits specified in Section 15.209(a).

10.6.Test Procedure
The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
ground(Below 1GHz). The EUT and its simulators are placed on a turntable, which is 1.5
meter high above ground(Above 1GHz). The turntable can rotate 360 degrees to
determine the position of the maximum emission level. EUT is set 3.0 meters away from
the receiving antenna, which is mounted on an antenna tower. The antenna can be moved
up and down between 1.0 meter and 4 meters to find out the maximum emission level.
Broadband antenna (calibrated bi-log antenna) is used as receiving antenna. Both
horizontal and vertical polarizations of the antenna are set on measurement. In order to
find the maximum emission levels, all of the EUT location must be manipulated
according to ANSI C63.10:2013 on radiated emission measurement. This EUT was tested
in 3 orthogonal positions and the worst case position data was reported.
During the radiated emission test, the spectrum analyzer was set with the following
configurations:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum
analyzer is 120kHz for Quasi-peak at frequency below 1GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz
and video bandwidth is 3MHz for peak measurement with peak detector
at frequency above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz
and video bandwidth is 10Hz for Average measurement with peak
detection at frequency above 1GHz.
4. All modes of operation were investigated and the worst-case emissions
are reported.

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.

spread spectrum or digitally modulated intentional radiator is operating, the radio
frequency power that is produced by the intentional radiator shall be at least 20 dB below
that in the 100 kHz bandwidth within the band that contains the highest level of the
desired power, based on either an RF conducted or a radiated measurement, provided the
transmitter demonstrates compliance with the peak conducted power limits. If the
transmitter complies with the conducted power limits based on the use of RMS averaging
over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation
required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the
general limits specified in Section 15.209(a) is not required. In addition, radiated
emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
comply with the radiated emission limits specified in Section 15.209(a).
11.3.EUT Configuration on Measurement
The equipment are installed on the emission Measurement to meet the commission
requirements and operating regulations in a manner which tends to maximize its emission
characteristics in normal application.
11.4.Operating Condition of EUT

Radiated Band Edge Result
Note:
1. Emissions attenuated more than 20 dB below the permissible value are not reported.
2. The field strength is calculated by adding the antenna factor, high pass filter loss(if
used) and cable loss, and subtracting the amplifier gain(if any)from the measured reading.
The basic equation calculation is as follows:
Result = Reading + Corrected Factor
3. Display the measurement of peak values.
Test Procedure:
The EUT and its simulators are placed on a turntable, which is 1.5 meter high above
ground(Above 1GHz). The turntable can rotate 360 degrees to determine the position of
the maximum emission level. EUT is set 3.0 meters away from the receiving antenna,
which is mounted on an antenna tower. The antenna can be moved up and down between
1.0 meter and 4 meters to find out the maximum emission level. Broadband antenna
(calibrated bi-log antenna) is used as receiving antenna. Both horizontal and vertical
polarizations of the antenna are set on measurement. In order to find the maximum
emission levels, all of the EUT location must be manipulated according to ANSI
C63.10:2013 on radiated emission measurement. This EUT was tested in 3 orthogonal
positions and the worst case position data was reported.
Let the EUT work in TX (Hopping off, Hopping on) modes measure it.
We select 2402MHz, 2480MHz TX frequency to transmit(Hopping off mode).
We select 2402-2480MHz TX frequency to transmit(Hopping on mode).
During the radiated emission test, the spectrum analyzer was set with the following
configurations:
1.The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 3MHz for peak measurement with peak detector at frequency above 1GHz.
2.The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 10Hz for Average measurement with peak detection at frequency above
1GHz.
3.All modes of operation were investigated and the worst-case(∏/4-DQPSK) emissions
are reported.
