FCC §15.203 - ANTENNA REQUIREMENT
Applicable Standard
According to § 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 user of a standard antenna jack or electrical connector
is prohibited. The structure and application of the EUT were analyzed to determine compliance with
section §15.203 of the rules. §15.203 state that the subject device must meet the following criteria:

a. Antenna must be permanently attached to the unit.
b. Antenna must use a unique type of connector to attach to the EUT.
Unit must be professionally installed, and installer shall be responsible for verifying that the correct
antenna is employed with the unit.

Antenna Information And Connector Construction
The EUT has 2 antennas use a unique type of connector to attach to the unit, and the antennas gain is 2.75

EMI Test Receiver & Spectrum Analyzer Setup

The system was investigated from 30 MHz to 25 GHz.

During the radiated emission test, the EMI test receiver & Spectrum Analyzer Setup were set with the
following configurations:

30-1000MHz:
Measurement RBW Video B/W IF B/W
QP 120 kHz 300 kHz 120kHz

1GHz- 25GHz:
Measurement Duty cycle RBW Video B/W
PK Any 1MHz 3 MHz
>98% 1MHz 10 Hz
Ave.
<98% 1MHz 1/T

Note: T is minimum transmission duration

Test Procedure

Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.

Data was recorded in Quasi-peak detection mode for frequency range of 30 MHz-1 GHz, peak and
Average detection modes for frequencies above 1 GHz.

All emissions under the average limit and under the noise floor have not recorded in the report.

Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the
Amplifier Gain from the Meter Reading. The basic equation is as follows:

Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain

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. The equation for margin
calculation is as follows:

Margin = Limit –Corrected Amplitude

FCC §15.247(b) (3) - MAXIMUM CONDUCTED OUTPUT POWER
Applicable Standard
According to FCC §15.247(b) (3), for systems using digital modulation in the 902-928 MHz, 2400-2483.5
MHz, and 5725-5850 MHz bands: 1 Watt. 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.
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. The
average must not include any time intervals during which the transmitter is off or is transmitting at a
reduced power level. 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.

Test Procedure
1. Place the EUT on a bench and set it in transmitting mode.
2. Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to test
equipment.
3. Add a correction factor to the display.

FCC§15.247(d) – 100 kHz BANDWIDTH OF FREQUENCY BAND EDGE
Applicable Standard
According to FCC§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 §15.209(a) is not
required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must
also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)).

Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
from an external generator.
2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect its
antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured
frequency within its operating range, and make sure the instrument is operated in its linear range.
3. Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span
including 100 kHz bandwidth from band edge.
4. Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the
graph with marking the highest point and edge frequency.
5. Repeat above procedures until all measured frequencies were complete.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG180227004-00

FCC §15.247(e) - POWER SPECTRAL DENSITY
Applicable Standard
According to FCC§15.247(e):For digitally modulated systems, the power spectral density conducted from
the intentional radiator to the antenna shall not be greater than 8 dBm in any 3 kHz band during any time
interval of continuous transmission. This power spectral density shall be determined in accordance with
the provisions of paragraph (b) of this section. The same method of determining the conducted output
power shall be used to determine the power spectral density.

Test Procedure
a) Set analyzer center frequency to DTS channel center frequency.
b) Set the span to 1.5 times the DTS bandwidth.
c) Set the RBW to: 3 kHz ≤ RBW ≤ 100 kHz.
d) Set the VBW ≥ 3×RBW.
e) Detector = RMS.
f) Sweep time = auto couple.
g) Trace mode = max hold.
h) Allow trace to fully stabilize.
i) Use the peak marker function to determine the maximum amplitude level within the RBW.
j) If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat.
