8.4 UNWANTED EMISSIONS INTO NON-RESTRICTED FREQUENCY BANDS 8.4.1 Applicable Standard According to FCC Part 15.247(d) and KDB 558074 DTS 01 Meas. Guidance v03r02 8.4.2 Conformance Limit According to FCC Part 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. 8.4.3 Test Configuration Test according to clause 7.1 radio frequency test setup 1 8.4.4 Test Procedure The transmitter output (antenna port) was connected to the spectrum analyzer  Reference level measurement Establish a reference level by using the following procedure: Set instrument center frequency to DTS channel center frequency. Set the span to ≥ 1.5 times the DTS bandwidth. Set the RBW = 100 kHz. Set the VBW ≥ 3 x RBW. Set Detector = peak. Set Sweep time = auto couple. Set Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum PSD level. Note that the channel found to contain the maximum PSD level can be used to establish the reference level.  Emission level measurement Set the center frequency and span to encompass frequency range to be measured. Set the RBW = 100 kHz. Set the VBW =300 kHz. Set Detector = peak Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum amplitude level. 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 . Report the three highest emissions relative to the limit. 8.4.5 Test Results All the modulation modes were tested, the data of the worst mode(802.11b) are described in the following table TRF No.: FCC 15.247/A Page 28 of 79 Report No.: ES150714157E3 Ver.1.0
