(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. For superregenerative receivers, an independent signal generator had been used to radiated an unmodulated were (cw) signal to the receiver at its operating frequency in order to “cohere” or resolve the individual components of the characteristic broadband emission from such a receiver. The level of such signal may need to be adjusted in order to accomplish this. (8) Measuring Uncertainty: The calculated uncertainty for measurement performed at 3M test distance are:- 30MHz to 300MHz = ± 3.7dB, 300MHz to 1000MHz = + 3.0dB/-2.7dB. 1GHz to 18GHz = +3.3dB/-3.4dB. Remark: Purpose of this test is to provide the Applicant with the necessary test data of their device for the submission to FCC with application for Equipment Authorization under FCC’s Equipment Authorization Program. This test itself is not an Approval Test. *** End of Document *** Date: 2000-07-17 TEST REPORT Page 5 of 5 No.: HM102920 TEST EQUIPMENT AUDIT Radiated Emission EQP NO.DESCRIPTIONMANUFACTURERMODEL NO.SERIAL NO.LAST CAL.
