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.
The Transmitter was operated in the normal operating mode. The TX frequency was fixed which was for the
purpose of the measurements.
Test of channel included the lowest and middle and highest frequency to perform the test, then record on this
report.
Those data rates (1Mbps for GFSK modulation; 2Mbps for π/4-DQPSK modulation; 3Mbps for 8-DPSK
modulation) were used for all test.
The EUT was pretested with 3 orientations placed on the table for the radiated emission measurement –X, Y,
and Z-plane. The X-plane results were found as the worst case and were shown in this report.

Test Procedure
According to the requirements in Section 13.1.4.1 of ANSI C63.10-2013 Conducted emissions the EUT
measured in the frequency range between 0.15 MHz and 30 MHz using CISPR Quasi-Peak and average
detector mode.
1. The EUT was placed 0.4 meter from the conducting wall of the shielding room.
2. The EUT was placed on a table which is 0.8m above ground plane.
3. Connect EUT 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.
4. 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 40cm long.
5. 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.
6. LISN at least 80 cm from nearest part of EUT chassis.
7. The frequency range from 150KHz to 30MHz was searched.
8. Set the test-receiver system to Peak Detect Function and specified bandwidth(IF bandwidth=9KHz) with
Maximum Hold Mode
9. For the actual test configuration, please refer to the related Item –EUT Test Photos.

Test Procedure
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the
standards: ANSI C63.10-2013. 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.
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:

a. The measuring distance of at 3 m shall be used for measurements at frequency up to 1GHz. For
frequencies above 1GHz, any suitable measuring distance may be used.
b. The EUT was placed on the top of a rotating table 0.8 m for below 1GHz and 1.5m for above 1GHz the
ground at a 3 meter. The table was rotated 360 degrees to determine the position of the highest
radiation.
c. The height of the equipment or of the substitution antenna shall be 0.8 m for below 1GHz and 1.5m for
above 1GHz; the height of the test antenna shall vary between 1 m to 4 m. Both horizontal and vertical
polarizations of the antenna are set to make the measurement.
d. For the radiated emission test above 1GHz:
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.
e. 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 Quasi
Peak detector mode re-measured.
f. 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.
g. 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

Note: for the frequency ranges below 30 MHz, a narrower RBW is used for these ranges but the measured
value should add a RBW correction factor (RBWCF) where RBWCF [dB] =10*lg(100 [kHz]/narrower RBW
[kHz]). , the narrower RBW is 1 kHz and RBWCF is 20 dB for the frequency 9 kHz to 150 kHz, and the
narrower RBW is 10 kHz and RBWCF is 10 dB for the frequency 150 kHz to 30 MHz.

DH3 Dwell time: Reading * (1600/4)*31.6/(channel number)
DH5 Dwell time: Reading * (1600/6)*31.6/(channel number)
For Example:
1. In normal mode, hopping rate is 1600 hops/s with 6 slots in 79 hopping channels.
With channel hopping rate (1600 / 6 / 79) in Occupancy Time Limit (0.4 x 79) (s),
Hops Over Occupancy Time comes to (1600 / 6 / 79) x (0.4 x 79) = 106.67 hops.
2. In AFH mode, hopping rate is 800 hops/s with 6 slots in 20 hopping channels.
With channel hopping rate (800 / 6 / 20) in Occupancy Time Limit (0.4 x 20) (s),
Hops Over Occupancy Time comes to (800 / 6 / 20) x (0.4 x 20) = 53.33 hops.
3.
Dwell Time(s) = Hops Over Occupancy Time (hops) x Package Transfer Time

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)).

The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator.
The path loss was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously.
The EUT must have its hopping function enabled.
Use the following spectrum analyzer settings:
Span = approximately 5 times the 20 dB bandwidth, centered on a hopping channel
RBW = 100KHz
VBW = 300KHz
Band edge emissions must be at least 20 dB down from the highest emission level within the authorized
band as measured with a 100kHz RBW. The attenuation shall be 30 dB instead of 20 dB when RMS
conducted output power procedure is used.
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.
Repeat above procedures until all measured frequencies were complete.

7.9 SPURIOUS RF CONDUCTED EMISSION
7.9.1
Applicable Standard
According to FCC Part 15.247(d) and ANSI C63.10-2013.
7.9.2
Conformance 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 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)).
7.9.3
Measuring Instruments
The Measuring equipment is listed in the section 6.3 of this test report.
7.9.4
Test Setup
Please refer to Section 6.1 of this test report.
7.9.5
Test Procedure
Establish an emission level by using the following procedure:
a) Set the center frequency and span to encompass frequency range to be measured.
b) Set the RBW = 100 kHz.
c) Set the VBW ≥ [3 × RBW].
d) Detector = peak.
e) Sweep time = auto couple.
f) Trace mode = max hold.
g) Allow trace to fully stabilize.
h) Use the peak marker function to determine the maximum amplitude level.
Then the limit shall be attenuated by at least 20 dB relative to the maximum
amplitude level in 100 kHz.
7.9.6
Test Results
Remark: The measurement frequency range is from 9KHz to the 10th harmonic of the fundamental
frequency. The lowest, middle and highest channels are tested to verify the spurious emissions and bandege
measurement data.
The worst mode is 8-DPSK mode, and the report only show the worst mode data.
