SETUP OF EQUIPMENT UNDER TEST
7.1
RADIO FREQUENCY TEST SETUP 1
The Bluetooth component’s antenna ports(s) of the EUT are connected to the measurement instrument per
an appropriate attenuator. The EUT is controlled by PC/software to emit the specified signals for the purpose
of measurements.
7.2
RADIO FREQUENCY TEST SETUP 2
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the
standards: ANSI C63.10. The test distance is 3m.The setup is according to the requirements in Section
13.1.4.1 of ANSI C63.10-2013 and CAN/CSA-CEI/IEC CISPR 22.
Below 30MHz:
The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the
antenna (loop antenna). The Antenna should be positioned with its plane vertical at the specified distance
from the EUT androtated about its vertical axis formaximum response at each azimuth about the EUT. The
center of the loopshall be 1 m above the ground.For certain applications, the loop antennaplane may also
need to be positioned horizontally at the specified distance from the EUT.
30MHz-1GHz:
The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the
antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable
azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0° to 360°,
and the receive antenna has two polarizations Vertical (V) and Horizontal (H).
Above 1GHz:
The EUT is placed on a turntable 1.5 meters above the ground in the chamber, 3 meter away from the
antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable
azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0° to 360°,

FREQUENCY HOPPING SYSTEM REQUIREMENTS
Standard Applicable
According to FCC Part 15.247(a)(1), 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.
(g) Frequency hopping spread spectrum systems are not required to employ all available hopping channels
during each transmission. However, the system, consisting of both the transmitter and the receiver, must be
designed to comply with all of the regulations in this section should the transmitter be presented with a
continuous data (or information) stream. In addition, a system employing short transmission bursts must
comply with the definition of a frequency hopping system and must distribute its transmissions over the
minimum number of hopping channels specified in this section.
(h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the
system to recognize other users within the spectrum band so that it individually and independently chooses
and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency
hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of
individual hopping frequencies by multiple transmitters is not permitted.
8.2
EUT Pseudorandom Frequency Hopping Sequence
The channel is represented by a pseudo-random hopping sequence hopping through the 79 RF channels.
The hopping sequence is unique for the piconet and is determined by the Bluetooth device address of the
master; thephase in the hopping sequence is determined by the Bluetooth clock of the master.The channel is
divide into time slots where each slot corresponds to an RF hop frequency. Consecutive hopscorrespond to
different RF hop frequencies. The normal hop is 1 600 hops/s.
The pseudorandom sequence may be generated in a nine-stage shift register whose 5th and 9th stage
outputs are added in a modulo-two addition stage, and the result is fed back to the input of the first stage.
The sequence begins with the first ONE of 9 consecutive ONEs; i.e. the shift register is initialized with nine
ones. Number of shift register stages: 9
Length of pseudo-random sequence: 29-1 = 524 bits
Longest sequence of zeros: 8 (non-inverted signal)

Each frequency used equally on the average by each transmitter.
The system receiver have input bandwidths that match the hopping channel bandwidths of their
corresponding transmitters and shift frequencies in synchronization with the transmitted signals.
8.3
Equal Hopping Frequency Use
All Bluetooth units participating in the piconet are time and hop-synchronized to the channel.
Example of a 79 hopping sequence in data mode:
35, 27, 6, 44, 14, 61, 74, 32, 1, 11, 23, 2, 55, 65, 29, 3, 9, 52, 78, 58, 40, 25, 0, 7, 18, 26, 76, 60, 47, 50, 2, 5,

Frequency Hopping System
This transmitter device is frequency hopping device, and complies with FCC part 15.247 rule.
This device uses Bluetooth radio which operates in 2400-2483.5 MHz band. Bluetooth uses a radio
technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits
chunks of it on up to 79 bands (1 MHz each; centred from 2402 to 2480 MHz) in the range 2,400-2,483.5
MHz. The transmitter switches hop frequencies 1,600 times per second to assure a high degree of data
security. All Bluetooth devices participating in a given piconet are synchronized to the frequency-hopping
channel for the piconet. The frequency hopping sequence is determined by the master's device address and
the phase of the hopping sequence (the frequency to hop at a specific time) is determined by the master's
internal clock. Therefore, all slaves in a piconet must know the master's device address and must
synchronize their clocks with the master's clock.
Adaptive Frequency Hopping (AFH) was introduced in the Bluetooth specification to provide an effective way
for a Bluetooth radio to counteract normal interference. AFH identifies "bad" channels, where either other
wireless devices are interfering with the Bluetooth signal or the Bluetooth signal is interfering with another
device. The AFH- enabled Bluetooth device will then communicate with other devices within its piconet to
share details of any identified bad channels. The devices will then switch to alternative available "good"
channels, away from the areas of interference, thus having no impact on the bandwidth used.

Test Procedure
The EUT was operating in Bluetooth v4.2 with classic mode and controlled its channel. Printed out the test
result from the spectrum by hard copy function.
The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator. The path loss
was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously
Set RBW = 30 kHz.
Set the video bandwidth (VBW) =100kHz.
Set Span= approximately 2 to 3 times the 20 dB bandwidth
Set Detector = Peak.
Set Trace mode = max hold.
Set Sweep = auto couple.
The EUT should be transmitting at its maximum data rate. Allow the trace to stabilize.Use the
marker-to-peak function to set the marker to the peak of the emission. Use themarker-delta function to
measure 20 dB down one side of the emission. Reset the markerdeltafunction, and move the marker to the
other side of the emission, until it is (asclose as possible to) even with the reference marker level. The
marker-delta reading atthis point is the 20 dB bandwidth of the emission.
If this value varies with differentmodes of operation (e.g., data rate, modulation format, etc.), repeat this test
for eachvariation.
Measure and record the results in the test report.

Test Configuration
Test according to clause 7.1 radio frequency test setup 1
9.6.4
Test Procedure
The transmitter output (antenna port) was connected to the spectrum analyzer
 Reference level measurement
Establish a reference level by using the following procedure:
Set instrument center frequency to DSS channel center frequency.
Set Span = approximately 5 times the 20 dB bandwidth, centered on a hopping channel.
Set the RBW = 100 kHz. Set the VBW ≥ 3 x RBW.
Set Detector = peak. Set Sweep time = auto couple.
Set Trace mode = max hold. Allow trace to fully stabilize.
Use the peak marker function to determine the maximum Maximumconducetedlevel.
Note that the channel found to contain the maximum conduceted level can be used to establish the
reference level.
 Band-edge Compliance of RF Conducted Emissions
Use the following spectrum analyzer settings:
Span = wide enough to capture the peak level of the emission operating on the channel closest to the
band-edge, as well as any modulation products which fall outside of the authorized band of operation
Set RBW ≥ 1% of the span=100kHzSet VBW ≥ RBW
Set Sweep = autoSetDetector function = peakSetTrace = max hold
Allow the trace to stabilize. Set the marker on the emission at the bandedge, or on the highest modulation
product outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta
function, then use the marker-to-peak function to move the marker to the peak of the in-band emission.
The marker-delta value now displayed must comply with the limit specified in this Section.
Now, using the same instrument settings, enable the hopping function of the EUT. Allow the trace to
stabilize. Follow the same procedure listed above to determine if any spurious emissions caused by the
hopping function also comply with the specified limit.
 Conduceted Spurious RF Conducted Emission
Use the following spectrum analyzer settings:
Span = wide enough to capture the peak level of the in-band emission and all spurious emissions (e.g.,
harmonics) from the lowest frequency generated in the EUT up through the 10th harmonic.(30MHz to
25GHz).Set RBW = 100 kHzSetVBW ≥ RBW
Set Sweep = autoSetDetector function = peakSetTrace = max hold
Allow the trace to stabilize. Set the marker on the peak of any spurious emission recorded. The level
displayed must comply with the limit specified in this Section.

Test Procedure
This test is required for any spurious emission that falls in a Restricted Band, as defined in Section 15.205.
It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the
following spectrum analyzer settings:
The EUT was placed on a turn table which is 0.8m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 1 MHz for f ≥ 1 GHz(1GHz to 25GHz), 100 kHz for f < 1 GHz(30MHz to 1GHz)
VBW ≥ RBW
Sweep = auto
Detector function = peak

Trace = max hold
Follow the guidelines in ANSI C63.10-2013 respect to maximizing the emission by rotating the EUT,
measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the
measurement antenna height and polarization, etc. A pre-amp and a high pass filter are required for this
test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The
peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is
the peak field strength, which must comply with the limit specified in Section 15.35(b). Submit this data.
Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level, once
corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the
hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be further adjusted
by a “duty cycle correction factor”, derived from 20log(dwell time/100 ms), in an effort to demonstrate
compliance with the 15.209 limit. Submit this data.
Repeat above procedures until all frequency measured was complete.

ANTENNA APPLICATION
Antenna Requirement
Standard
FCC CRF Part15.203
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. This requirement does not apply to carrier
current devices or to devices operated under the provisions of §15.211,
§15.213, §15.217,§15.219, or §15.221. Further, this requirement does
not apply to intentionalradiators that must be professionally installed,
such as perimeter protection systems and some field disturbance
sensors, or to other intentional radiators which, in accordance with
§15.31(d), must be measured at the installation site. However, the
installer shall be responsible for ensuring that the proper antenna is
employed so that the limits in this part are not exceeded.
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. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of
directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the
directional gain of the antenna exceeds 6dBi.
9.9.2
Result
The EUT’S antenna is PCB antenna. The antenna’s gain is -0.58 dbi, and the antenna can’t be replaced by
the userwhich in accordance to section 15.203, please refer to the photos.
