 TEST SETUP



Testing Frequency/Channel/Port Selection:


         L(owest), M(iddle), H(ighest) Channels of 900MHz Band.
         Measured at EUT’s antenna connector on PCB for conducted measurements
         1.0dBi gain antenna is used for radiated emission test.
         Channel Selection: Low Channel=902.6MHz; Middle Channel=915.2MHz; High
          Channel=927.2MHz
         For intentional radiator measurements, only 900MHz Band transmitter was activated. The rest
          circuitry was set as Standby/ Receiving mode during the test. Based on pre-scan results, the
          configuration, VAC4-Wi-Fi-MultiProx, was chosen as the worst case for final data collection.

 CALCULATIONS per FCC requirements

 Given
         E =  (30 * P * G) / d
 and
         S = E ^ 2 / 3770
 where
         E = Field Strength in Volts/meter
         P = Power in Watts
         G = Numeric antenna gain
         d = Distance in meters
         S = Power Density in milliwatts/square centimeter

 Combining equations and rearranging the terms to express the distance as a function of the remaining
 variables yields:
          d =  ((30 * P * G) / (3770 * S))

 Changing to units of Power to mW and Distance to cm, using: P
        (mW) = P (W) / 1000 and
        d (cm) =100 * d (m)
 yields
        d = 100 *  ((30 * (P / 1000) * G) / (3770 * S))
        d = 0.282 *  (P * G / S)
 where
        d = distance in cm
        P = Power in mW
        G = Numeric antenna gain
        S = Power Density in mW/cm^2

 Substituting the logarithmic form of power and gain using: P
          (mW) = 10 ^ (P (dBm) / 10) and
          G (numeric) = 10 ^ (G (dBi) / 10)
 yields
          d = 0.282 * 10 ^ ((P + G) / 20) /  S                    Equation (1)

         S = 0.0795 * 10 ^ ((P + G)/10)/ d^2                       Equation (2)
 where
         d = MPE distance in cm
         P = Power in dBm
         G = Antenna Gain in dBi
         S = Power Density Limit in mW/cm^2

 Equation (1) and the measured peak power is used to calculate the MPE distance.
 Equation (2) and the measured peak power is used to calculate the Power density.

 From §1.1310 Table 1 (B),
 for Public S = 1.0 mW/cm2

 NOTE: For mobile or fixed location transmitters, the minimum separation distance is 20 cm, even if
 calculations indicate that the MPE distance would be less.

 CALCULATIONS per IC requirements

** To use this conducted testing method, per 12.2.2-12.2.6, the followings shall be taken as consideration:
      1. Proper RBW and detector, per 15.35 a/b, shall be chosen in different frequency ranges;
      2. Maximum transmitter antenna gain ( no less than 2dBi), G, shall be added to the measured power level to
           determine the EIRP;
      3. Appropriate factor, A, shall be added to model worst case ground reflections: 6.0dB (f≤30MHz ) and 4.7dB ( f≤30 to
           1000MHz)
      4. Electric field strength can be obtained from the equation: E= EIRP-20log(d)+104.8+G (or 2.0) +A; Then compare to
           applicable limit;
      5. Unwanted emissions from EUT cabinet or casing shall be measured via radiated emission test method per C63.10 ( in this
           case, the antenna port may be terminated properly).
      6. Absolute peak power limit of -21.2dBm within the unwanted emission bandwidth shall be used for meeting 15.35(b)
           requirement;
      7. Per 15.35(c), for pulse operation, Duty Cycle factor reduction can be applied for unwanted emissions that have the same
           pulse characteristics as does the fundamental emissions ( such as harmonics) pulse operation
*** EUT shall be configured to transmit continuously (min. 98% duty cycle at full power). The spectrum analyzer shall be set for
bin-to-bin spacing ≤RBW/2.

 §15.209 (b) In the emission table above, the tighter limit applies at the band edges.

TEST PROCEDURE

 The EUT is placed on a non-conducting table 80 cm above the ground plane. The antenna to EUT distance is
 3 meters. The EUT is configured in accordance with ANSI C63.4. The EUT is set to transmit in a continuous
 mode. Established procedures in C63.10 for performing radiated measurements shall be used. For cabinet
 emission measurements, the EUT transmit antenna may be replaced with a termination matching the
 nominal impedance of the antenna. For portable devices, the EUT was tested in three orthogonal planes.

 For measurements below 1 GHz the resolution bandwidth is set to 100 kHz for peak detection
 measurements or 120 kHz for quasi-peak detection measurements. Peak detection is used unless otherwise
 noted as quasi-peak. For measurements above 1 GHz the resolution bandwidth is set to 1 MHz, and then the
 video bandwidth is set to 1 MHz for peak measurements and 10 Hz for average measurements.

 The radio spectrum was investigated from the lowest frequency generated within the device (without going
 below 9 kHz) up to the 10th harmonic of the rated transmitted emission. The emissions are investigated with
 the transmitter set to the lowest, middle, and highest channels.

 The emissions are investigated with the transmitter set to the lowest, middle, and highest channels, if
 applicable. The frequency range of interest is monitored at a fixed antenna height and EUT azimuth. The
 EUT is rotated through 360 degrees to maximize emissions received. The antenna is scanned from 1 to 4
 meters above the ground plane to further maximize the emission. Measurements are made with the antenna
 polarized in both the vertical and the horizontal positions.

 No non-compliance noted:
