Radiated Spurious Emissions: [§15.235(a),(b)] 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. The device was tested three orthogonal planes. 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: Operating Frequency : 49.860 MHz Distance of Measurement : 3.0 meters Antenna Meter Reading Field Strength at 3 m Frequency Factor Horiz. Vert. Horiz. Vert.

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 49.860 MHz 10 (AF+Mr)/20 = 10 (3.6+59.8)/20 = 1479.1 m V/m Where, Af = Antenna Factor including the cable loss. Mr = Meter Reading 5.
