1. The testing follows the guidelines in ANSI C63.10-2013 clause 6.4.
2. The EUT was arranged to its worst case and then turntable (from 0 degree to 360 degrees) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level. Both Horizontal, Face-on and Face-off polarizations of the antenna are set to make the measurement.
3. The EUT was placed on a turntable with 80 cm above ground.
4. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a 1 m height antenna tower.
5. The radiated emission limits are based on measurements employing a CISPR quasi-peak detector except for the frequency bands 9-90 kHz, 110-490 kHz and above 1000 MHz Radiated emission limits in these three bands are based on measurements employing an average detector.
6. For measurement below 1 GHz, 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 and average detector mode remeasured. If the emission level of the EUT measured by the peak detector is 3 dB lower than the applicable limit, the peak emission level will be reported. Otherwise, the emission measurement will be repeated using the quasi-peak and average detector and reported.
7. Although these tests were performed other than open field site, adequate comparison measurements were confirmed against 30m open field site. Therefore sufficient tests were made to demonstrate that the alternative site produces results that correlate with the ones of tests made in an open field site based on KDB 414788.

8. The limits in CFR 47, Part 15, Subpart C, paragraph 15.209 (a), are identical to those in RSSGEN Section 8.9, Table 6, since the measurements are performed in terms of magnetic field strength and converted to electric field strength levels (as reported in the table) using the free space impedance of 377. For example, the measurement frequency X kHz resulted in a level of Y dBuV/m, which is equivalent to Y-51.5 = Z dBuA/m, which has the same margin, W dB, to the corresponding RSS-GEN Table 6 limit as it has to be 15.209(a) limit.

1. The testing follows the guidelines in ANSI C63.10-2013 clause 6.5.
2. The EUT was arranged to its worst case and then tune the antenna tower (from 1 m to 4 m) and turntable (from 0 degree to 360 degrees) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level. Both horizontal and vertical polarizations of the antenna are set to make the measurement.
3. The EUT was placed on a turntable with 80 cm above ground.
4. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower.
5. For measurement below 1 GHz, 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. If the emission level of the EUT measured by the peak detector is 3 dB lower than the applicable limit, the peak emission level will be reported. Otherwise, the emission measurement will be repeated using the quasi-peak detector and reported.

Above 1 GHz The setting of the spectrum analyzer

RBW VBW Sweep Detector Trace

1 MHz 3 MHz Auto Peak Max hold

1. The testing follows the guidelines in ANSI C63.10-2013 clause 6.6.
2. The EUT was arranged to its worst case and then tune the antenna tower (from 1 m to 4 m) and turntable (from 0 degree to 360 degrees) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level. Both horizontal and vertical polarizations of the antenna are set to make the measurement.
3. The EUT was placed on a turntable with 1.5 m above ground.
4. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower.
5. For measurement above 1 GHz, the emission measurement will be measured by the peak detector. This peak level, once corrected, must comply with the limit specified in Section 15.209.
6. For measurements above 1 GHz the resolution bandwidth is set to 1 MHz, then the video bandwidth is set to 3 MHz for peak measurements. AVG Result=Peak Result + Duty Cycle Correction Factor. For the + Duty Cycle Correction Factor please refer to clause 7.2. ON TIME AND DUTY CYCLE.

X axis, Y axis, Z axis positions:

Note: For all radiated test, EUT in each of three orthogonal axis emissions had been tested, but only the worst case (X axis) data recorded in the report.

TEST PROCEDURE
For Restricted Bandedge and field strength of intentional emission: Note: 1. Measurement = Reading Level + Correct Factor. 2. If the peak values are less than the average limit of 54 dBuV/m, the average result is deemed to comply with average limit. 3. Peak: Peak detector. 4. AVG Result=Peak Result + Duty Cycle Correction Factor. 5. For the transmitting duration, please refer to clause 7.2. 6. Only the worst data was recorded, if it complies with the limit, the other emissions deemed to comply with the limit. 7. Both horizontal and vertical have been tested, only the worst data was recorded in the report. 8. All modes, channels and antennas have been tested, only the worst data was recorded in the report.
For Radiate Spurious emission (9 kHz ~ 30 MHz): Note: 1. Measurement = Reading Level + Correct Factor. 2. If the peak values are less than the QP limit, the QP result is deemed to comply with QP limit. 3. All 3 polarizations (Horizontal, Face-on and Face-off) of the loop antenna had been tested, but only the worst data recorded in the report. 4. All modes, channels and antennas have been tested, only the worst data was recorded in the report.
For Radiate Spurious Emission (30 MHz ~ 1 GHz): Note: 1. Result Level = Read Level + Correct Factor. 2. If the peak values are less than the QP limit, the QP result is deemed to comply with QP limit. 3. All modes, channels and antennas have been tested, only the worst data was recorded in the report.

For Radiate Spurious Emission (1 GHz ~ 3 GHz): 1. Measurement = Reading Level + Correct Factor. 2. If the peak values are less than the average limit of 54 dBuV/m, the average result is deemed to comply with average limit. 3. Peak: Peak detector. 4. AVG Result=Peak Result + Duty Cycle Correction Factor. 5. For the transmitting duration, please refer to clause 7.2. 6. Filter losses were only considered in the spurious frequency bands and the authorized band was not corrected for Band reject filter losses. 7. Proper operation of the transmitter prior to adding the filter to the measurement chain. 8. All modes, channels and antennas have been tested, only the worst data was recorded in the report.
For Radiate Spurious Emission (3 GHz ~ 18 GHz): Note: 1. Peak Result = Reading Level + Correct Factor. 2. If the peak values are less than the average limit of 54 dBuV/m, the average result is deemed to comply with average limit. 3. Peak: Peak detector. 4. AVG Result=Peak Result + Duty Cycle Correction Factor. 5. For the transmitting duration, please refer to clause 7.2. 6.

9. ANTENNA REQUIREMENT
REQUIREMENT Please refer to FCC part 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. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. 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.
