BSL Testing Co.,LTD. Report No.:BSL18061126490001 9. Out of Band Emissions 9.1 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, 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). 9.2 Test Procedure According to the KDB 558074 D01 v04, the band-edge radiated test method as follows: Set span = wide enough to capture the peak level of the emission operating on the channel closest to the bandedge, as well as any modulation products which fall outside of the authorized band of operation (2310MHz to 2420MHz for low bandedge, 2460MHz to 2500MHz for the high bandedge) RBW = 1MHz, VBW = 1MHz for peak value measured RBW = 1MHz, VBW = 10Hz for average value measured Sweep = auto; Detector function = peak/average; Trace = max hold All the trace to stabilize, set the marker on the emission at the bandedge, or on the highest modulation product outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta function, then use the marker-to-peak function to move the marker to the peak of the in-band emission. Those emission must comply with the 15.209 limit for fall in the restricted bands listed in section 15.205. Note that the method of measurement KDB publication number: 913591 may be used for the radiated bandedge measurements. According to the KDB 558074 D01 v04, the conducted spurious emissions test method as follows: 1. Set start frequency to DTS channel edge frequency. 2. Set stop frequency so as to encompass the spectrum to be examined. 3. Set RBW = 100 kHz. 4. Set VBW ≥ 300 kHz. 5. Detector = peak. 6. Trace Mode = max hold. 7. Sweep = auto couple. 8. Allow the trace to stabilize (this may take some time, depending on the extent of the span). 9. Use peak marker function to determine maximum amplitude of all unwanted emissions within any 100 kHz bandwidth. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) are attenuated by at least the minimum requirements specified in section 8.1. Report the three highest emissions relative to the limit. Page 26 of 31 FCC Part 15.247
