Notes:
1). Measuring frequencies from 9 KHz~10th harmonic or 26.5GHz (which is less), No emission found
between lowest internal used/generated frequency to 30MHz.
2). Radiated emissions measured in frequency range from 9k~10th harmonic or 26.5GHz (which is less)
were made with an instrument using Peak detector mode.
3). Data of measurement within this frequency range shown “ --- ” in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small to
be measured.

5.6. Conducted Spurious Emissions and Band Edges Test
5.6.1. Standard Applicable

According to §15.247 (d): 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. Attenuation below the general limits specified in Section 15.209(a) is not required. In
addition, radiated emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
comply with the radiated emission limits specified in Section 15.209(a) (see Section 15.205(c)).

5.6.2. Measuring Instruments and Setting

Please refer to section 6 of equipment list in this report. The following table is the setting of the spectrum
analyzer.

Spectrum Parameter Setting
Detector Peak
Attenuation Auto
RB / VB (Emission in restricted band) 100KHz/300KHz
RB / VB (Emission in non-restricted band) 100KHz/300KHz

5.6.3. Test Procedures

The transmitter output is connected to a spectrum analyzer. The resolution bandwidth is set to 100 kHz.
The video bandwidth is set to 300 kHz
The spectrum from 9 kHz to 26.5GHz is investigated with the transmitter set to the lowest, middle, and
highest channels.

5.6.4. Test Setup Layout

This test setup layout is the same as that shown in section 5.4.4.

5.6.5. EUT Operation during Test

The EUT was programmed to be in continuously transmitting mode.

5.6.6. Test Results of Conducted Spurious Emissions

PASS
Please refer to Appendix B BT V4.2 (BT LE) Test Data Section B.5 for conducted spurious
emissions;
Please refer to Appendix B BT V4.2 (BT LE) Test Data Section B.6 for conducted band edge
emission.

Remark:
1). Test results including cable loss;
2). “---“means that the fundamental frequency not for 15.209 limits requirement.
3). Not recorded emission from 9 KHz to 30 MHz as emission level at least 20dBc lower than emission
limit.

D = specified measurement distance in meters.
11). Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
conservative antenna gain value is necessary. Thus, when determining the EIRP based on the measured
conducted power, the upper bound on antenna gain for a device with a single RF output shall be selected
as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever is greater.
However, for devices that operate in multiple frequency bands while using the same transmit antenna, the
highest gain of the antenna within the operating band nearest in frequency to the restricted band emission
being measured may be used in lieu of the overall highest gain when the emission is at a frequency that is
within 20 percent of the nearest band edge frequency, but in no case shall a value less than 2 dBi be used.
12). Compare the resultant electric field strength level to the applicable regulatory limit.
13). Perform radiated spurious emission test duress until all measured frequencies were complete.

5.8.5 Test Results

PASS
Please refer to Appendix B BT V4.2 (BT LE) Test Data Section B.7
Remark:
1). Test results including cable loss;
2). “---“means that the fundamental frequency not for 15.209 limits requirement;
3). The average measurement was not performed when the peak measured data under the limit of
average detection.
4). Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=10Hz/Sweep time=Auto/Detector=Peak.
5). Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
conservative antenna gain value is necessary. Thus, when determining the EIRP based on the measured
conducted power, the upper bound on antenna gain for a device with a single RF output shall be selected
as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever is greater.
However, for devices that operate in multiple frequency bands while using the same transmit antenna, the
highest gain of the antenna within the operating band nearest in frequency to the restricted band emission
being measured may be used in lieu of the overall highest gain when the emission is at a frequency that is
within 20 percent of the nearest band edge frequency, but in no case shall a value less than 2 dBi be
used.
