TEST CONFIGURATION
TEST PROCEDURE
1.
The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
manual. The EUT is a tabletop system; a wooden table with a height of 0.8 meters is used and is placed on
the ground plane as per ANSI C63.10:2013.
2.
Support equipment, if needed, was placed as per ANSI C63.10:2013.
3.
All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10:2013.
4.
The adapter received AC120V/60Hz power through a Line Impedance Stabilization Network (LISN) which
supplied power source and was grounded to the ground plane.
5.
All support equipments received AC power from a second LISN, if any.
6.
The EUT test program was started. Emissions were measured on each current carrying line of the EUT
using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two
monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1
connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1
connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.
7.
Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
8.
During the above scans, the emissions were maximized by cable manipulation.

3.2. Radiated Emissions and Band Edge
Limit
For intentional device, according to § 15.209(a), the general requirement of field strength of radiated
emission out of authorized band shall not exceed the following table at a 3 meters measurement
distance.
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)

Test Procedure
1.
Below 1GHz measurement the EUT is placed on a turntable which is 0.8m above ground plane,
and above 1GHz measurement EUT was placed on a low permittivity and low loss tangent turn
table which is 1.5m above ground plane.
2.
Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating
the turn table from 0℃ to 360℃ to acquire the highest emissions from EUT
3.
And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.
4.
Repeat above procedures until all frequency measurements have been completed.
TEST RESULTS
Remark:
1. We measured Radiated Emission at GFSK, π/4 DQPSK and 8DPSK mode from 9 KHz to 25GHz
and recorded worst case at GFSK DH5 mode.
2. For below 1GHz testing recorded worst at GFSK DH5 low channel.
3. Radiated emission test from 9 KHz to 10th harmonic of fundamental was verified, and no emission
found except system noise floor in 9 KHz to 30MHz and not recorded in this report.

3.8. Out-of-band Emissions
Limit
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 con-ducted or a radiated
measurement, pro-vided the transmitter demonstrates compliance with the peak conducted power
limits. If the transmitter com-plies 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.
Test Procedure
Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum
analyzer to RBW=100 kHz, VBW= 300 kHz, peak detector , and max hold. Measurements utilizing
these setting are made of the in-band reference level, bandedge and out-of-band emissions.

Remark: The measurement frequency range is from 30MHz to the 10th harmonic of the fundamental
frequency. The lowest, middle and highest channels are tested to verify the spurious emissions and

3.9. Pseudorandom Frequency Hopping Sequence
TEST APPLICABLE
For 47 CFR Part 15C section 15.247 (a) (1) requirement:
Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum
of 25 kHz or the 20 dB bandwidth of the hop-ping 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
hop-ping channel bandwidths of their corresponding transmitters and shall shift frequencies in
synchronization with the transmitted signals.
EUT Pseudorandom Frequency Hopping Sequence Requirement
The pseudorandom frequency hopping sequence may be generated in a nice-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, for example:
the shift register is initialized with nine ones.
● Number of shift register stages:9
● Length of pseudo-random sequence:29-1=511 bits
● Longest sequence of zeros:8(non-inverted signal)
An example of pseudorandom frequency hopping sequence as follows:
Each frequency used equally one the average by each transmitter.
The system receiver have input bandwidths that match the hopping channel bandwidths of their
corresponding transmitter and shift frequencies in synchronization with the transmitted signals.

Antenna Requirement
Standard Applicable
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 (c), 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.
Refer to statement below for compliance
The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a
standard antenna jack or electrical connector is prohibited. Further, this requirement does not apply to
intentional radiators that must be professionally installed.
Antenna Connected Construction
The maximum gain of antenna was 0dBi.
