CONDUCTED SPURIOUS EMISSION COMPLIANCE TEST 11.1.Block Diagram of Test Setup 11.2.The Requirement For Section 15.247(d) 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, 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 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). 11.3.EUT Configuration on Measurement The equipment is installed on the emission measurement to meet the commission requirements and operating regulations in a manner which tends to maximize its emission characteristics in normal application. 11.4.Operating Condition of EUT 11.4.1.Setup the EUT and simulator as shown as Section 11.1. 11.4.2.Turn on the power of all equipment. 11.4.3.Let the EUT work in TX modes measure it.
