2. System Test Configuration
2.1 EUT Configuration
The EUT configuration for testing is installed on RF field strength measurement to
meet the Commissions requirement and operating in a manner which intends to
maximize its emission characteristics in a continuous normal application.
2.2 Special Accessories
Not available for this EUT intended for grant.
2.3 Description of test modes
The EUT has been tested under operating condition. Test program used to control the
EUT for staying in continuous transmitting and normal mode is programmed. The
Lowest, middle and highest channel were chosen for testing, and all packets DH1,
DH3 and DH5 mode in all modulation type GFSK, π/4-DQPSK, 8DPSK were tested.
2.4 EUT Exercise
The EUT was operated in the engineering mode to fix the Tx frequency that was for
the purpose of the measurements.

4.2 Measurement Procedure
a. Blow 1GHz, the EUT was placed on the top of a rotating table 0.8 meters above the
ground at a 3 meter semi- anechoic chamber room.
b. For the radiated emission test above 1GHz:
The EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3
meter full anechoic chamber room. The table was rotated 360 degrees to determine the
position of the highest radiation. Place the measurement antenna away from each area of
the EUT determined to be a source of emissions at the specified measurement distance,
while keeping the measurement antenna aimed at the source of emissions at each
frequency of significant emissions, with polarization oriented for maximum response. The
measurement antenna may have to be higher or lower than the EUT, depending on the
radiation pattern of the emission and staying aimed at the emission source for receiving
the maximum signal. The final measurement antenna elevation shall be that which
maximizes the emissions. The measurement antenna elevation for maximum emissions
shall be restricted to a range of heights of from 1 m to 4 m above the ground or reference
ground plane.
c. The EUT was set 3 meters away from the interference-receiving antenna, which was
mounted on the top of a variable-height antenna tower.
d. The height of antenna is varied from one meter to four meters above the ground to
determine the maximum value of the field strength. Both horizontal and vertical
polarizations of the antenna are set to make the measurement.
e. For each suspected emission, the EUT was arranged to its worst case and then the
antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned
from 0 degrees to 360 degrees to find the maximum reading. The test-receiver system
was set to peak detect function and specified bandwidth with maximum hold mode.
f. A Quasi-peak measurement was then made for that frequency point for below 1GHz test.

field strength limits are based on average detector, however,
the peak field strength of any emission shall not exceed the
maximum permitted average limits, specified above by more
than 20dB under any condition of modulation.
(4) The frequency range scanned is from the lowest radio
frequency signal generated in the device which is greater than
9 kHz to the tenth harmonic of the highest fundamental
frequency or 40 GHz, whichever is lower.

6.1 Measurement Procedure
Maximum 20dB RF Bandwidth, FCC Rule 15.247(a)(1):
The antenna port of the EUT was connected to the input of a spectrum analyzer.
Analyzer RBW was chosen so that the display was a result of the hopping channel
modulation. For each RF output channel investigated, the spectrum analyzer center
frequency was set to the channel carrier. Use the spectrum 20dB down delta
function to measure the bandwidth.

11. Antenna Application
11.1 Antenna requirement
According to of FCC part 15C section 15.203 and 15.240:
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, 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.
Systems operating in the 2400-2483.5MHz band that are used exclusively for fixed,
point-to-point operations may employ transmitting antennas with directional gain
greater than 6dBi provided the maximum peak output power of the intentional
radiator is reduced by 1dB for every 3dB that the directional gain of the antenna
exceeds 6dBi.
11.2 Measurement Results
The antenna is PCB antenna and no consideration of replacement, and the best
case gain of the antenna is -0.68 dBi. So, the antenna is consider meet the
requirement.
