FCC ID: K6620534X20 REPORT #: Y\YAESU\245AUT13\245AUT13TestReport.doc Page 6 of 11 TEST PROCEDURE General: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. Radiation Interference: The test procedure used was ANSI C63.4 -2003 using a spectrum analyzer with a pre-selector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The video bandwidth was always greater than or equal to the RBW. Formula Of Conversion Factors: The field strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBμV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the preselector was accounted for in the spectrum analyzer Meter Reading. Example: Freq (MHz) Meter Reading + ACF +CL = FS 33 20 dBμV + 10.36 dB/m +0.40 dB =30.76 dBμV/m @ 3m ANSI C63.4-2003 Section 10.1.7 Measurement Procedures: The unit under test was placed on a table 80 cm high and with dimensions of 1mby 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and verticals planes. If power line conducted testing was required for this device, the situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSI C63.4-2003…
