(2) Distance between the ET and measuring antenna: 3 meters. (3) Measuring instrumentations: CISPR Quasi-peak type field strength meter (25 MHz - 1000 MHz and 1GHz-18GHz ).6dB bandwidth set at 120KHz. Also, peak level of the fundamental emissions was measured in order to determine compliance with the 20dB peak to average limit specified in Section 15.231 of the FCC new Rules. (4) Measuring antenna: Broad band antenna for the frequency range 25-1000 MHz, connected with 10 meters coaxial cable.Horn antenna for the frequency range 1-18 GHz, connected with high frequency coaxial cable.Cable loss of the coaxial cable. Cable included in the Antenna Factor for measurement data. The antenna are capable of measuring both horizontal and vertical polarizations. (5) Frequency range scanned: The frequency range from 25 MHz to 1000 MHz had been searched. Readings of the highest emissions relating to the limit were reported as above. (6) Arrangement of EUT: During the test, the sample was operated at rated supply voltage and arranged for maximum emissions. (7) Measuring Procedure: In accordance with the relevant clauses of the FCC Rules Part 15 section 15.109(a) and ANSI C63.4:1992 section 12.1.1.1-2. (8) Measuring Uncertainty: The calculated uncertainty for measurement performed at 3M test distance are:- 30MHz to 200MHz = ± 3.7dB, 200MHz to 1000MHz = + 3…
