No. I19Z61038-EMC02 Page 11 of 17 ANNEX A: MEASUREMENT RESULTS A.1 OUTPUT POWER Reference FCC: CFR Part 90.635, and 2.1053 A.1.1 Summary During the process of testing, the EUT was controlled via Agilent Universal Radio Communication Tester (E5515C) to ensure max power transmission and proper modulation. This result contains peak output power and ERP/EIRP measurements for the EUT. In all cases, output power is within the specified limits. A.1.2 Radiated A.1.2.1 Description This is the test for the maximum radiated power from the EUT. Rule Part 90.635(b) specifies "The maximum output power of the transmitter for mobile stations is 100 watts (20 dBw).” A.1.2.2 Method of Measurement The measurements procedures in TIA-603-E-2016 are used. 1. EUT was placed on a 1.5 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 1.5m. The test setup refers to figure below. 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 three channels (High, Middle, Low) were measured with RMS detector. 2. The EUT is then put into continuously transmitting mode at its maximum power level during the test. And the maximum value of the receiver should be recorded as (Pr). 3. The EUT shall be replaced by a substitution antenna. The test setup refers to figure below. ©Copyright. All rights reserved by CTTL.

No. I19Z61038-EMC02 Page 12 of 17 In the chamber, a 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. Adjust the level of the signal generator output until the value of the receiver reaches 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. 4. An amplifier should be connected to the Signal Source output port. And the cable should be connected 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 - Pcl - Ga 5. This value is EIRP since the measurement is calibrated using an antenna of known gain (Unit dBi) and known input power. 6. ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP -2.15. For test layout photo, please refer to Pic.1 in Annex B.

No. I19Z61038-EMC02 Page 14 of 17 A.2 EMISSION LIMT Reference FCC: CFR Part 90.691 and 2.1053 A.2.1 Measurement Method The measurements procedures in TIA-603-E-2016 are used. This measurement is carried out in fully-anechoic chamber 3. The spectrum was scanned from 30 MHz to the 10th harmonic of the highest frequency generated within the equipment, which is the transmitted carrier that can be as high as 1910 MHz. The resolution bandwidth is set 1MHz as outlined in CFR Part 90.691. The spectrum was scanned with the mobile station transmitting at carrier frequencies that pertain to low, mid and high channels of CDMA800 BC10. The procedure of radiated spurious emissions is as follows: 1. EUT was placed on a 1.5 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 1.5m. The test setup refers to figure below. 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 non-harmonic and harmonics of the transmit frequency through the 10th harmonic were measured with peak detector. 2. The EUT is then put into continuously transmitting mode at its maximum power level during the test. And the maximum value of the receiver should be recorded as (Pr). 3. The EUT shall be replaced by a substitution antenna. The test setup refers to figure below. ©Copyright. All rights reserved by CTTL.

No. I19Z61038-EMC02 Page 15 of 17 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. Adjust the level of the signal generator output until the value of the receiver reaches 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. 4. The Path loss (Ppl) between the Signal Source with the Substitution Antenna and the Substitution Antenna Gain (Ga) should be recorded after test. An amplifier should be connected in for the test. The Path loss (Ppl) is the summation of the cable loss and the gain of the amplifier. The measurement results are obtained as described below: Power (EIRP) = PMea+ Ppl + Ga 5. This value is EIRP since the measurement is calibrated using an antenna of known gain (unit: dBi) and known input power. 6. ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP -2.15dB. A.2.2 Measurement Limit CFR Part 90.691 all specify that the power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB. The specification that emissions shall be attenuated below the transmitter power (P) by at least 43 + 10 log (P) dB, translates in the relevant power range (1 to 0.001 W) to -13 dBm. At 1 W the specified minimum attenuation becomes 43 dB and relative to a 30 dBm (1 W) carrier becomes a limit of -13 dBm. At 0.001 W (0 dBm) the minimum attenuation is 13 dB, which again yields a limit of -13 dBm. In this way a translation of the specification from relative to absolute terms is carried out. A.2.3 Measurement Results Radiated emissions measurements were made only at the upper and lower carrier frequencies of the CDMA BC10 (817.9MHz and 823.1MHz). It was decided that measurements at these two carrier frequencies would be sufficient to demonstrate compliance with emissions limits because it was seen that all the significant spurs occur well outside the band and no radiation was seen from a carrier in one block of the CDMA BC10 into any of the other blocks. The equipment must still, however, meet emissions requirements with the carrier at all frequencies over which it is capable of operating and it is the manufacturer's responsibility to verify this. ©Copyright.
