Limit (dBm) = P( dBm)-50-10 log (Pwatts) = -20dBm FCC Part 95.2779 (b)(7) 43 + 10 log(P) dB on any frequency removed from the channel center frequency by more than 50 kHz Limit (dBm) = P( dBm)-43-10 log (Pwatts) = -13dBm TEST CONFIGURATION TEST PROCEDURE 1. The RF output of the EUT was connected to a spectrum analyzer through appropriate attenuation. 2. The resolution bandwidth of the spectrum analyzer was set to 100 kHz. Sufficient scans were taken to show any out of band emission up to 10th. Harmonic for the lower and the highest frequency range. 3. Set RBW 100 kHz, VBW 300 kHz in the frequency band 30MHz to 1GHz,while set RBW=1MHz.VBW=3MHz from the 1GHz to 10th Harmonic. 4. The audio input was set the unmodulated carrier, the resulting picture is print out for each channel separation.

Transmitter Radiated Spurious Emission Radiated spurious emissions are emissions from the equipment when transmitting into a nonradiating load on a frequency or frequencies that are outside an occupied band sufficient to ensure transmission of information of required quality for the class of communications desired.

Report No : TRE1801017701 Page 22 of 33 Issued: 2018—02—06 C 5 Receiving Antenna 3 $§ TEST PROCEDURE 1. Standard Transmitter Load with a 50 2| input impedance and an output impedance matched to the test equipment. 2. EUT was placed on a 0.8 meter high non—conductive stand at a 3 meter test distance from the receive antenna. A receiving antenna was placed on the antenna mast 3 meters from the EUT for emission measurements. The height of receiving antenna is 1. 0 m. Detected emissions were maximized at each frequency by rotating the EUT through 360° and adjusting the receiving antenna polarization. The radiated emission measurements of all transmit frequencies in six channels were measured with peak detector. A log—periodic antenna or double—ridged waveguide horn antenna shall be substituted in place of the EUT. The log—periodic antenna will be driven by a signal generator and the level will be adjusted till the same power value on the spectrum analyzer or receiver. The level of the spurious emissions can be calculated through the level of the signal generator, cable loss, the gain of the substitution antenna and the reading of the spectrum analyzer or receiver. The EUT is then put into continuously transmitting mode at its maximum power level during the test.Set Test Receiver or Spectrum RBW=1MHz, VBW=3MHz for above 1GHz and RBW=100kHz, VBW=300kHz for 30MHz to 1GHz, And the maximum value of the receiver should be recorded as (Pr). The EUT shall be replaced by a substitution antenna. In the chamber, an substitution antenna for the frequency band of interest is placed at the reference point of the chamber. An RF Signal source for the frequency band of interest is connected to the substitution antenna with a cable that has been constructed to not interfere with the radiation pattern of the antenna. A power (PMea) is applied to the input of the substitution antenna, and adjust the level of the signal generator output until the value of the receiver reach the previously recorded (Pr). The power of signal source (PMea) is recorded. The test should be performed by rotating the test item and adjusting the receiving antenna polarization. A amplifier should be connected to the Signal Source output port. And the cable should be connect between the Amplifier and the Substitution Antenna. The cable loss (Pcl) ,the Substitution Antenna Gain (Ga) and the Amplifier Gain (PAg) should be recorded after test. The measurement results are obtained as described below: Power{EIRP)=PMea— PAg — Pol — Ga We used SMF100A micowave signal generator which signal level can up to 33dBm,so we not used power Amplifier for substituation test; The measurement results are amend as described below: Power{EIRP)=PMea— Pol — Ga 7. This value is EIRP since the measurement is calibrated using an antenna of known gain (2.15 dBi) and known input power. 8. ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP—2.15dBi. TEST MODE: Please reference to the section 3.4 TEST RESULTS B Passed [_] Not Applicable
