[ ] yes, [ ] no 4.4 Was the EUT used for periodic transmissions at regular predetermined intervals ? [ ] yes, [ x ] no Ref. Report No. 03 - 341 – 020 Page 6 of 14 Korea Testing Laboratory Telecommunication Team 222-13, Guro3-dong, Guro-gu, Seoul Korea 152-848 . RADIATED EMISSION MEASUREMENT (Section 15.231) 1. Test Procedure 1.1 Preliminary Testing for Reference 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 (Biconi-Log antenna : 26 to 2000 MHz or Horn Antenna : 1 to 18 GHz) 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. Emission levels 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 an Absorber-Lined Room The final measure…

Sample Calculation The measured field strength was determined by averaging one complete pulse train including blanking interval because the pulse repetition time of the EUT(=76.2ms) does not exceeds 0.1 seconds (15.35(c)). See graphs of page 12 . With the resolution bandwidth set at 10 kHz, the EUT produces a pulse spectrum on the spectrum analyzer because the bandwidth of the analyzer is greater than or equal to the PRF (= 417 Hz). Therefore, as mentioned in HP Application Note 150-2 (page 11), the pulse desensitization(a p ) equals zero and the display amplitude is essentially a peak level. .
