No. I19Z61038-WMD02 Page12 of 27 ANNEX A: MEASUREMENT RESULTS A.1 OUTPUT POWER A.1.1 Summary During the process of testing, the EUT was controlled via Agilent Wireless Communications Test Set (8960(E5515C)) to ensure max power transmission and proper modulation. This result is peak output power conducted measurements for the EUT. In all cases, output power is within the specified limits. A.1.2 Method of Measurements The EUT was set up for the max output power with pseudo random data modulation. The power was measured with Rhode & Schwarz Spectrum Analyzer FSV30 (average). These measurements were done at 2 frequencies of CDMA BC10 (bottom and top of operational frequency range) for 1x RTT and 1xEVDO. The measurement method is from KDB 971168 D01 5.2.1: a) Set span to at least 1.5 times the OBW. b) Set RBW = 1-5% of the OBW, not to exceed 1 MHz. c) Set VBW ≥ 3 × RBW. d) Set number of points in sweep ≥ 2 × span / RBW. e) Sweep time = auto-couple. f) Detector = RMS (power averaging). g) If the EUT can be configured to transmit continuously (i.e., burst duty cycle ≥ 98%), then set the trigger to free run. h) If the EUT cannot be configured to transmit continuously (i.e., burst duty cycle < 98 %), then use a sweep trigger with the level set to enable triggering only on full power bursts and configure the EUT to transmit at full power for the entire duration of each sweep. Ensure that the sweep time is less than or equal to the transmission burst duration. i) Trace average at least 100 traces in power averaging (i.e., RMS) mode. j) Compute the power by integrating the spectrum across the OBW of the signal using the instrument’s band power measurement function, with the band limits set equal to the OBW band edges. If the instrument does not have a band power function, then sum the spectrum levels (in linear power units) at intervals equal to the RBW extending across the entire OBW of the spectrum. ©Copyright.

No. I19Z61038-WMD02 Page14 of 27 A.2 FREQUENCY STABILITY A.2.1 Method of Measurement In order to measure the carrier frequency under the condition of AFC lock, it is necessary to make measurements with the EUT in a “call mode”. This is accomplished with the use of Agilent 8960(E5515C) Wireless Communications Test Set. 1. Measure the carrier frequency at room temperature. 2. Subject the EUT to overnight soak at -10℃. 3. With the EUT, powered via nominal voltage, connected to the 8960(E5515C) and in a simulated call on mid channel of CDMA BC10, measure the carrier frequency. These measurements should be made within 2 minutes of Powering up the EUT, to prevent significant self-warming. 4. Repeat the above measurements at 10℃ increments from -10℃ to +50℃. Allow at least 1 1/2 hours at each temperature, unpowered, before making measurements. 5. Remeasure carrier frequency at room temperature with nominal voltage. Vary supply voltage from minimum voltage to maximum voltage, in 0.1Volt increments remeasuring carrier frequency at each voltage. Pause at nominal voltage for 1 1/2 hours unpowered, to allow any self-heating to stabilize, before continuing. 6. Subject the EUT to overnight soak at +50℃. 7. With the EUT, powered via nominal voltage, connected to the 8960(E5515C) and in a simulated call on the centre channel, measure the carrier frequency. These measurements should be made within 2 minutes of Powering up the EUT, to prevent significant self-warming. 8. Repeat the above measurements at 10 C decrements from +50℃ to -10℃. Allow at least 1 1/2 hours at each temperature, unpowered, before making measurements. 9. At all temperature levels hold the temperature to +/- 0.5℃ during the measurement procedure. A.2.2 Measurement Limit A.2.2.1 For Hand carried battery powered equipment The frequency stability shall be sufficient to ensure that the fundamental emission stays within the authorized frequency block. This requires that the lower voltage for frequency stability testing be specified by the manufacturer. This transceiver is specified to operate with an input voltage of between 3.7VDC and 4.4VDC, with a nominal voltage of 3.85VDC. Operation above or below these voltage limits is prohibited by transceiver software in order to prevent improper operation as well as to protect components from overstress. A.2.2.2 For equipment powered by primary supply voltage For Part 90.213, the frequency stability of the transmitter shall be maintained within ±2.5ppm of the center frequency. This requires varying primary supply voltage from 85 to 115 percent of the nominal value for other than hand carried battery equipment. ©Copyright. All rights reserved by CTTL.

No. I19Z61038-WMD02 Page20 of 27 A.5 CONDUCTED SPURIOUS EMISSION A.5.1 Measurement Method The spectrum should be investigated from the lowest radio frequency generated in the equipment up to at least the 10th harmonic of the carrier frequency. For CDMA BC10, data taken from 30 MHz to 10GHz. Out-of-band emission requirement shall apply only to the ‘‘outer’’ channels included in an EA license and to spectrum adjacent to interior channels used by incumbent licensees. The emission limits are as follows: For any frequency removed from the EA licensee’s frequency block by up to and including 37.5 kHz, the power of any emission shall be attenuated below the transmitter power (P) in watts by at least 116Log10(f/6.1) decibels or 50 + 10 Log10(P) decibels or 80 decibels, whichever is the lesser attenuation, where f is the frequency removed from the center of the outer channel in the block in kilohertz and where f is greater than 12.5 kHz. For any frequency removed from the EA licensee’s frequency block greater than 37.5 kHz, the power of any emission shall be attenuated below the transmitter power (P) in watts by at least 43 + 10Log10(P) decibels or 80 decibels, whichever is the lesser attenuation, where f is the frequency removed from the center of the outer channel in the block in kilohertz and where f is greater than 37.5 kHz.
