Radiated Spurious Emissions: [§15.109(a)] Measurement Method Employed: Measurements were made under the conditions specified ANSI C63.4. The field strength measurements of the equipment under test were made at the distance of 3 meters away from the device which was placed on the wooden turntable 0.8 meter in height. The receiving antenna polarized horizontally was varied from 1 to 4 meters and the wooden turntable was rotated through 360 degrees to obtain the highest reading on the field strength meter. These measurements were repeated with the receiving antenna polarized vertically. The internal pre-amplifier was used from 30 MHz up to 1000 MHz. Measurement Results: Tuning Frequency : 49.860 MHz Distance of Measurement : 3.0 meters Antenna Meter Reading Field Strength at 3 m Frequency Factor Horizontal Vertical Horizontal Vertical (MHz) (dB) (dB/ m V) (dB/ m V) ( m V/m) ( m V/m) 48.831 3.4 2.3 3.8 1.9 2.3 58.337 5.0 0.2 4.5 1.8 3.0 236.000 18.0 7.6 < -5.0 19.1 < 4.5 243.890 18.3 7.4 < -5.0 19.3 < 4.6 248.992 18.5 6.9 < -5.0 18.6 < 4.7 249.987 18.6 6.0 0.5 17.0 9.0 Note: 1.The spectrum was checked from 30 MHz to 1000 MHz. All emissions not listed were found to be more than 20 dB below the limits. 2.The symbol of “<” means “or less”. 3.The cable loss was included in the antenna factor. 4.Sample calculation : At 48.831 MHz 10 (Af+Mr)/20 = 10 (3.4+3.8)/20 = 2.3 m V/m Where, Af = Antenna Factor including the cable loss. Mr = Meter Reading 5.Measuring Instrument Setting: Detector function : CISPR quasi-peak IF Bandwidth : 120 kHz JQA Application No. :80-81036 FCC ID :CVTRN6230 Model No. :RN6230 Issue Date :April 13, 1999 Standard :CFR 47 FCC Rules Part 15 Page 3 of 6 JQA QUALITY ASSURANCE ORGANIZATION JQA Application No. :80-81036 FCC ID :CVTRN6230 Model No. :RN6230 Issue Date :April 13, 1999 Standard :CFR 47 FCC Rules Part 15 Page 4 of 6 JQA QUALITY ASSURANCE ORGANIZATION MEASUREMENT SET-UP FOR RADIATED EMISSIONS Turn Table EUT 3 m 1 m 0.8 m Half-wave Dipole Antenna Field Strength Meter Ground Plane 4 m Biconical Antenna Signal Generator JQA Application No. :80-81036 FCC ID :CVTRN6230 Model No. :RN6230 Issue Date :April 13, 1999 Standard :CFR 47 FCC Rules Part 15 Page 5 of 6 JQA QUALITY ASSURANCE ORGANIZATION Configuration of EUT JQA Application No. :80-81036 FCC ID :CVTRN6230 Model No. :RN6230 Issue Date :April 13, 1999 Standard :CFR 47 FCC Rules Part 15 Page 6 of 6 JQA QUALITY ASSURANCE ORGANIZATION LIST OF MEASUREMENT EQUIPMENT Equipment (Model No.) Manufacturer Date of Cal. 1.
