All emissions not reported above are all well below the limit. Note:1. Unless otherwise indicated, the recorded readings are in quasi-peak values. 2. ** Calculation of radiation (average) : Formula : Duty cycle = (N1L1 + N2L2 + ... + Nn-1Ln-1 + NnLn) / 100 or T where N1 is number of type 1 pluse, L1 is length of type 1 pulse, etc. T is the period of the pulse train (if less than 100 ms) According to the time domain plots shown in page 10 & 11 : Duty cycle of the EUT = (4x1.52 + 40x0.52) / 47.4 = 0.567 Av correction factor = 20 x log(0.567) dB = - 4.92 dB Radiation (average) = Radiation (peak) + Av correction factor Radiation (average) of the EUT (Horizontal) = 66 - 4.92 dB(μV/m) = 61 dB(μV/m) Radiation (average) of the EUT (Vertical) = 70 - 4.92 dB(μV/m) = 65 dB(μV/m) 3. The measurement is conducted with the sample placed on the turnable in 3 orthogonal planes.

Measurement facility: Measurement facility located at Fanling (Hong Kong), placed on file with the FCC Pursuant to Section 2.948 of the FCC Rules (FCC Registration No. : 97774). 2. Distance between the EUT and measuring antenna: 3 meters. 3. Measuring instrumentations: Rohde & Schwarz ESH3 Test Receiver (9kHz – 30MHz), ESVP Test Receiver ( 20 - 1300 MHz ) with a CISPR weighting QP detector, 6 dB bandwidth set at 120 KHz. 4. Measuring antenna: Broad-band antenna for the frequency range 30 - 1000 MHz, connected with 10 meters coaxial cable. Cable loss of the coaxial cable included in the Antenna Factor for measurement data. The antenna is capable of measuring both horizontal and vertical polarizations. The antenna w…
