Test of Band Edges Emission 10.1 Applicable Standard Section 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. In addition, radiated emissions that fall in the restricted bands, as defined in Section 15.205, must also comply with the radiated emission limits specified in Section 15.209. 10.2 EUT Setup Radiated Measurement Setup Conducted Measurement Setup 10.3 Test Equipment List and Details See section 2.5. 10.4 Test Procedure Conducted Measurement 1. The transmitter is set to the lowest channel. 2. The transmitter output was connected to the spectrum analyzer via a cable . Spectrum Analyzer Report No.: BCT13AR012E Page 51 of 74 FCC ID: 2ABMEK1 3. Set both RBW and VBW of spectrum analyzer to 100KHz with convenient frequency span including 100MHz bandwidth from lower band edge. Then detector set to peak and max hold this trace. 4. The lowest band edges emission was measured and recorded. 5. The transmitter set to the highest channel and repeated 2~4. Radiated Measurement 1. Configure the EUT according to ANSI C63.4-2003 2. The turntable was rotated by 360 degrees to determine the position of the highest radiation. 3. The height of the broadband receiving antenna was varied between one meter and four meters above ground to find the maximum emission field strength of both horizontal and vertical polarization. 4. For band edge emission, the antenna tower was scan (from 1 M to 4 M) and then the turn table was rotated (from 0 degree to 360 degrees) to find the maximum reading. 5. For band edge emission, use 1MHz VBW and 1MHz RBW for reading under AV and use 1MHz VBW and 1MHz RBW for reading under PK. 10.5 Test Result Temperature ( °C ) : 22~23 EUT: Bluetooth Sunglasses Humidity (%RH ): 50~54 M/N: K1 Barometric Pressure ( mbar ): 950~1000 Operation Condition: Tx Mode Radiated Test Result Worst Case BDR 1M Frequency (MHz) Antenna Polarization Emission Read Value (dBμV/m) Limits (dBμV/m) 2389.5 H 34.12 54 2389.5 V 33.45 54 2483.6 H 35.22 54 2483.6 V 33.64 54 Worst Case EDR 2M Frequency (MHz) Antenna Polarization Emission Read Value (dBμV/m) Limits (dBμV/m) 2389.4 H 33.43 54 2389.4 V 32.55 54 2483.7 H 35.89 54 2483.7 V 33.65 54 Report No.: BCT13AR012E Page 52 of 74 FCC ID: 2ABMEK1 Worst Case EDR 3M Frequency (MHz) Antenna Polarization Emission Read Value (dBμV/m) Limits (dBμV/m) 2389.5 H 35.33 54 2389.5 V 33.24 54 2483.6 H 35.68 54 2483.6 V 34.24 54 Report No.: BCT13AR012E Page 53 of 74 FCC ID: 2ABMEK1 Conducted Test Result BDR 1M Low Channel High Channel Report No.: BCT13AR012E Page 54 of 74 FCC ID: 2ABMEK1 EDR 2M Low Channel High Channel Report No.: BCT13AR012E Page 55 of 74 FCC ID: 2ABMEK1 EDR 3M Low Channel High Channel Report No.: BCT13AR012E Page 56 of 74 FCC ID: 2ABMEK1 Hopping Mode Worst case BDR 1M Low High Report No.: BCT13AR012E Page 57 of 74 FCC ID: 2ABMEK1 11. Test of Spurious Radiated Emission 11.1 Applicable Standard Section 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.
