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 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)). 9.1 Test Procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum; 2. Set the spectrum analyzer: Blow 30MHz: RBW = 100kHz, VBW = 300kHz, Sweep = auto Detector function = peak, Trace = max hold Above 30MHz: RBW = 100kHz, VBW = 300kHz, Sweep = auto Detector function = peak, Trace = max hold Reference No.: WTU26D02040331W002 Page 31 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 9.2 Test Result GFSK (LE 1M)_channel 0 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 32 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 33 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn GFSK (LE 1M)_channel 19 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 34 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 35 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn GFSK (LE 1M)_channel 39 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 36 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 37 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn GFSK (LE 2M)_channel 0 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 38 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 39 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn GFSK (LE 2M)_channel 19 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 40 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 41 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn GFSK (LE 2M)_channel 19 Ref 9kHz-150kHz 150kHz-10MHz 10MHz-30MHz Reference No.: WTU26D02040331W002 Page 42 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 30MHz-25GHz Reference No.: WTU26D02040331W002 Page 43 of 55 Waltek Testing Group Co., Ltd. http://www.waltek.com.cn 10 Band Edge Measurement Test Requirement: FCC 47CFR Part 15 Section 15.247 Test Method: KDB 558074 D01 15.247 Meas Guidance v05r02, April 2, 2019 Test Limit: Regulation 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) (see §15.205(c)). Test Mode: Transmitting 10.1 Test Produce 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. 3. Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span including 100 kHz bandwidth from band edge. 4. Meas…
