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) 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.

Note:
1. The engineering test program was provided and the EUT was programmed to be in continuously
transmitting mode.
2. AC power line Conducted Emission was tested under maximum output power.
3. For radiated test cases, the worst mode data rate 1Mbps was reported only, because this data rate
has the highest RF output power at preliminary tests, and no other significantly frequencies found in
conducted spurious emission.
4. EUT is set to continuous transmission mode. duty cycle greater than 98%.

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

[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.

Test Procedure
The testing follows Measurement Procedure 10.3 Method AVGPSD of FCC KDB Publication No. 558074
D01 DTS Meas. Guidance v04
This procedure may be used when the maximum (average) conducted output power was used to
demonstrate compliance to the output power limit. This is the baseline method for determining the maximum
(average) conducted PSD level. If the instrument has an RMS power averaging detector, it must be used;
otherwise, use the sample detector. The EUT must be configured to transmit continuously (duty cycle ≥
98%); otherwise sweep triggering/signal gating must be implemented to ensure that measurements are
made only when the EUT is transmitting at its maximum power control level (no transmitter off time is to be
considered).
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 was operating in controlled its channel.
a) Set instrument center frequency to DTS channel center frequency.
b) Set span to at least 1.5 times the OBW.
c) Set RBW to: 3 kHz ≤ RBW ≤ 100 kHz. .
d) Set VBW ≥3 x RBW.
e) Detector = power averaging (RMS) or sample detector (when RMS not available).
f) Ensure that the number of measurement points in the sweep ≥ 2 x span/RBW.
g) Sweep time = auto couple.
h) Employ trace averaging (RMS) mode over a minimum of 100 traces.
i) Use the peak marker function to determine the maximum amplitude level.
j) If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat (note that this may require
zooming in on the emission of interest and reducing

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.

The Spurious RF conducted emissions compliance of RF radiated emission should be measured by
following the guidance in ANSI C63.10-2013 with respect to maximizing the emission by rotating the EUT,
measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the
measurement antenna height and polarization etc. Set RBW=100kHz and VBW= 300KHz to measure the
peak field strength , and measure frequeny range from 9KHz to 26.5GHz.
