2.2 DESCRIPTION OF TEST MODES
To investigate the maximum EMI emission characteristics generates from EUT, the test system
was pre-scanning tested base on the consideration of following EUT operation mode or test
configuration mode which possible have effect on EMI emission level. Each of these EUT
operation mode(s) or test configuration mode(s) mentioned above was evaluated respectively.

3.1.2 TEST PROCEDURE
a. The EUT was 0.8 meters from the horizontal ground plane and 0.4 meters from the vertical
ground plane with EUT being connected to the power mains through a line impedance
stabilization network (LISN). All other support equipments powered from additional LISN(s).
The LISN provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument.
b. Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
and forth in the center forming a bundle 30 to 40 cm long.
c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall
length shall not exceed 1 m.
d. LISN at least 80 cm from nearest part of EUT chassis.
e. For the actual test configuration, please refer to the related Item –EUT Test Photos.

3.2.2 TEST PROCEDURE
a. The measuring distance of at 3 m shall be used for measurements at frequency 0.009MHz up
to 1GHz,and above 1GHz.
b. The EUT was placed on the top of a rotating table 0.8 meters(above 1GHz is 1.5 m) above the
ground at a 3 meter anechoic chamber test site. The table was rotated 360 degrees to
determine the position of the highest radiation.
c. The height of the equipment shall be 0.8 m(above 1GHz is 1.5 m); the height of the test
antenna shall vary between 1 m to 4 m. horizontal and vertical polarizations of the antenna are
set to make the measurement.
d. The initial step in collecting conducted emission data is a spectrum analyzer peak detector
mode pre-scanning the measurement frequency range. Significant peaks are then marked and
then QuasiPeak detector mode re-measured.
e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the
EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement
performed.
f. For the actual test configuration, please refer to the related Item –EUT Test Photos.
Note:
Both horizontal and vertical antenna polarities were tested
and performed pretest to three orthogonal axis. The worst case emissions were reported

3.2.6 FIELD STRENGTH CALCULATION
The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting
the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The basic
equation with a sample calculation is as follows:
FS = RA + AF + CL - AG
Where
FS = Field Strength
CL = Cable Attenuation Factor (Cable Loss)
RA = Reading Amplitude
AG = Amplifier Gain
AF = Antenna Factor

Note:
1)
Scan with GFSK, π/4-DQPSK,8DPSK,the worst case is GFSK Mode
2)
Factor = Antenna Factor + Cable Loss – Pre-amplifier.
Emission Level = Reading + Factor
The frequency emission of peak points that did not show above the forms are at least 20dB below the limit, the frequency
3)
emission is mainly from the environment noise.

4. CONDUCTED SPURIOUS & BAND EDGE EMISSION
4.1 REQUIREMENT
According to FCC section 15.247(d), in any 100kHz 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 20dB below that in
the 100kHz bandwidth within the band that contains the highest level of the desired power, based
on either an RF conducted or a radiated measurement.

Remark : Hopping on and Hopping off mode all have been tested,only worst case hopping off is
reported.
4.3 TEST SETUP
The EUT is coupled to the Spectrum Analyzer; the RF load attached to the EUT antenna terminal is
50Ohm; the path loss as the factor is calibrated to correct the reading. Make the measurement with
the spectrum analyzer's resolution bandwidth(RBW) = 100 kHz. In order to make an accurate
measurement, set the span greater than RBW.
4.4 EUT OPERATION CONDITIONS
The EUT tested system was configured as the statements of 2.3 Unless otherwise a special
operating condition is specified in the follows during the testing.

a. The transmitter output (antenna port) was connected to the spectrum analyzer
b. Set RBW =1MHz/VBW =3MHz.
c. Use a video trigger with the trigger level set to enable triggering only on full pulses.
d. Sweep Time is more than once pulse time.
Set the center frequency on any frequency would be measure and set the frequency span to
e. zero span.
f. Measure the maximum time duration of one single pulse.
g. Set the EUT for DH5, DH3 and DH1 packet transmitting.
h. Measure the maximum time duration of one single pulse.
i. DH5 Packet permit maximum 1600/ 79 / 6 = 3.37 hops per second in each channel (5 time
slots RX, 1 time slot TX). Sothe dwell time is the time duration of the pulse times 3.37 x 31.6
= 106.6 within 31.6 seconds.
j. DH3 Packet permit maximum 1600 / 79 / 4 = 5.06 hops per second in each channel (3 time
slots RX, 1 time slot TX). Sothe dwell time is the time duration of the pulse times 5.06 x 31.6 =
160 within 31.6 seconds.
k. DH1 Packet permit maximum 1600 / 79 /2 = 10.12 hops per second in each channel (1 time
slot RX, 1 time slot TX). So the dwell time is the time duration of the pulse times 10.12 x 31.6 =
320 within 31.6 seconds.

7. HOPPING CHANNEL SEPARATION MEASUREMEN
7.1 APPLIED PROCEDURES / LIMIT
Frequency hopping systems shall have hopping channel carrier frequencies separated by a
minimum of 25 kHz or the 20 dB bandwidth of the hopping 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.

7.2 TEST PROCEDURE
a. The transmitter output (antenna port) was connected to the spectrum analyser in peak hold
mode.
b. The resolution bandwidth of 30 kHz and the video bandwidth of 100 kHz were utilised for 20
dB bandwidth measurement.
c. The resolution bandwidth of 30 kHz and the video bandwidth of 100 kHz were utilised for
channel separation measurement.
7.3 TEST SETUP
7.4 EUT OPERATION CONDITIONS
The EUT was programmed to be in continuously transmitting mode.
