7.1 RADIO FREQUENCY TEST SETUP 1
The Bluetooth 4.0 DTS 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 and rotated about its vertical axis for maximum response at each azimuth about the EUT. The
center of the loop shall be 1 m above the ground. For certain applications, the loop antenna plane 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°,
and the receive antenna has two polarizations Vertical (V) and Horizontal (H).

8.2.3 Test Configuration
Test according to clause 7.1 radio frequency test setup 1
8.2.4 Test Procedure
According to FCC Part15.247(b)(3)
As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a
measurement of the maximum conducted output power. For smart system, Maximum Conducted Output
Power is defined as the total transmit power delivered to all antennas and antenna elements averaged
across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control
level. Power must be summed across all antennas and antenna elements. If multiple modes of operation are
possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total
transmit power occurring in any mode.
Set the RBW DTS bandwidth(about 1MHz).
Set VBW =3*RBW(about 3MHz)
Set the span 3*RBW
Set Sweep time = auto couple.
Set Detector = peak.
Set Trace mode = max hold.
Allow trace to fully stabilize. Use peak marker function to determine the peak amplitude level.
According to FCC Part 15.247(b)(4):
Conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with
directional gains that do not exceed 6 dBi. If transmitting antennas of directional gain greater than 6 dBi are
used, the conducted output power from the intentional radiator shall be reduced below the stated values in
paragraphs (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna
exceeds 6 dBi.

Use the peak marker function to determine the maximum amplitude level.
Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding

8.5.4 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

Access to the World
Follow the guidelines in ANSI C63.10-2013 with 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.

8.7 ANTENNA APPLICATION
8.7.1 Antenna Requirement
Standard Requirement
FCC CRF Part 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. 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 intentional radiators 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.
8.7.2 Result
There is a PCB antenna for the product, and the antenna gain is 0 dBi.
The antenna can’t be replaced by the user, which in accordance to section 15.203, please refer to the
internal photos.
