Report No. 99 - 341 - 020 Sheet 5 of 10 Sheets . RADIATED EMISSION MEASUREMENT (Section 15.109) 1. Test Procedure 1.1 Preliminary Testing for Reference This pager receiver(EUT) is designed to operate in the band 139.050MHz to 169.800MHz by changing a local oscillator installed in internal PCB. According to section 15.31(m), the measurements were performed with three equipments which were selected as bottom, middle, and top frequency in the operating band. Preliminary testing was performed in a KTL absorber-lined room to determine the emission characteristics of the EUT. The EUT was placed on the wooden table which has dimensions of 0.8 meters in height, 1 meter in length and 1.5 meters in width. Receiving antenna(Biconical antenna : 30 to 300MHz, Log-periodic antenna : 200 to 1000MHz or Horn Antenna : 1 to 18GHz) was placed at the distance of 1 meter from the EUT. An attempt was made to maximize the emission level with the various configurations of the EUT while rotating the table and varying antenna height. Emissions level from the EUT with various configurations were examined on a Spectrum Analyzer connected with a RF amplifier and graphed by a plotter. 1.2 Final Radiated Emission Test at a Absorber-Lined Room The final measurement of radiated field strength was carried out in a KTL Absorber-Lined Room that was listed up at FCC according to the "Radiated Emissions Testing" procedure specified by ANSI C63.4. Based on the test results in preliminary test, measurement was made in same test set up and configuration which produced maximum emission level. Receiving antenna was installed at 3-meter distance from the EUT, and was connected to an EMI receiver or spectrum analyzer(for above 1GHz) with a RF amplifier. Turntable was rotated through 360 degrees and receiving antenna height was varied from 1 to 4 meters above the ground plane to read maximum emission level. If necessary, the radiated emission measurements could be performed at a closer distance than s…
