TEST REFERENCE: FCC Rules Part 15 section 15.239(88.00-108.00 MHz) TEST CONDITION: Normal TEST DATE : 2000.04.11. RESULTS AND NOTES The bandwidth of the emission shall be no wider than 200kHz of the center frequency for devices operating within 88.00MHz to 108.00MHz. The bandwidth is determind at the points 26dB down from the modulated carrier.

(2) Distance between the EUT and measuring antenna: 3 meters. (3) Measuring instrumentations: CISPR Quasi-peak type field strength meter (25 MHz - 1000 MHz). 6 dB 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 15.35(b) of the FCC new Rules. (4) Measuring antenna: Broad band antenna for the frequency range 25-1000 MHz, connected with 10 meters coaxial cable. Cable loss of the coaxial 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 emssions relating to the limit were reported as above. (6) Arrangement…
