PEAK OUTPUT POWER OF THE BASE Standard: FCC Part 15 Test procedure: paragraph 15.247 Test equipment: TYPE BRAND EMITECH NUMBER Spectrum analyzer FSP 40 Rohde & Schwarz 4088 Antenna RGA60 Electrometrics 1204 Open site EMITECH 1274 Radio frequency generator SME06 Rohde & Schwarz 1669 High pass filter HPM11630 Micro-tronics 1673 Low-noise amplifier 1 to 18 GHz ALC 2648 Variac R213 Dereix 1419 Power meter 8541B Gigatronics 3479 Power sensor 80401A Gigatronics 3182 Test set up: The system is tested in an open area test site (OATS). The test unit is placed on a rotating table, 0.8 m from a ground plane. Zero degree azimuth corresponds to the front of the equipment under test. We use for this measure outdoor test site,. The measuring distance between the equipment and the test antenna is 3 m. The antenna have been oriented in the two polarizations, we have recorded only highest level. Measurement of the electro-magnetic field is realized, with a resolution bandwidth and video bandwidth adjusted at 1 MHz with a peak detector. Distance of antenna: 3 meters Antenna height: 1 to 4 meters Antenna polarization: vertical and horizontal Equipment under test operating condition: The equipment is blocked in continuous transmission mode, modulated by internal data signal.

Results: Ambient temperature (°C): 19 Relative humidity (%): 36 Polarization of test antenna: horizontal (height: 239 cm) Position of equipment: use position (azimuth: 249 degrees) Sample n° 1 Channel 1 (Low channel) Level Cable loss Antenna Electro-magnetic P* dBµV dB factor field (W) dB (dBµV/m): Normal test Nominal power source 74.25 4.41 27.77 106.43 7.99 x 10-3 conditions (V): 115 Sample n° 1 Channel 40 (middle channel) Level Cable loss Antenna Electro-magnetic P* dBµV dB factor field (W) dB (dBµV/m): Normal test Nominal power source 75.26 4.41 27.77 107.44 10.08 x 10-3 conditions (V): 115 Sample n° 1 Channel 79 (high channel) Level Cable loss Antenna Electro-magnetic P* dBµV dB factor field (W) dB (dBµV/m): Normal test Nominal power source 75.49 4.41 27.77 107.67 10.63 x 10-3 conditions (V): 115 * P = (E x d)² / 30.Gp, with d=3 and Gp = 1.65 Test conclusion: RESPECTED STANDARD
