FCC ID: SS4SF550 Report No.: LCS1512161386E-02 4 TEST CONDITIONS AND RESULTS 4.1 Output Power TEST APPLICABLE During the process of testing, the EUT was controlled via R&S Digital Radio Communication tester (CMU200) to ensure max power transmission and proper modulation. This result contains output power and EIRP measurements for the EUT. In all cases, output power is within the specified limits. 4.1.1. Conducted Output Power TEST CONFIGURATION TEST PROCEDURE Conducted Power Measurement: a) Place the EUT on a bench and set it in transmitting mode. b) Connect a low loss RF cable from the antenna port to a CMU200 by an Att. c) EUT Communicate with CMU200 then selects a channel for testing. d) Add a correction factor to the display CMU200, and then test.

SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD. FCC ID: SS4SF550 Report No.: LCS1512161386E-02 4.1.1 Radiated Output Power TEST DESCRIPTION This is the test for the maximum radiated power from the EUT. Rule Part 24.232(c) specifies, "Mobile/portable stations are limited to 2 watts e.i.r.p. Peak power" and 24.232(e) specifies that "Peak transmit power must be measured over any interval of continuous transmission using instrumentation calibrated in terms of an rms-equivalent voltage." Rule Part 22.913(a) specifies ” The ERP of mobile transmitters and auxiliary test transmitters must not exceed 7 Watts.” TEST CONFIGURATION TEST PROCEDURE 1. EUT was placed on a 1.50 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 1.50m. 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 peak detector. 2. 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. 3.

The spectrum is scanned with the mobile station transmitting at carrier frequencies that pertain to low, mid and high channels of WCDMA Band II WCDMA Band IV and WCDMA Band V. TEST CONFIGURATION TEST PROCEDURE 1. EUT was placed on a 1.50 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 1.50 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 three channels (High, Middle, Low) were measured with peak detector. 2. 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. 3. 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, And the maximum value of the receiver should be recorded as (Pr). 4.

FCC ID: SS4SF550 Report No.: LCS1512161386E-02 4.5 Spurious Emssion on Antenna Port TEST APPLICABLE The following steps outline the procedure used to measure the conducted emissions from the EUT. 1. Determine frequency range for measurements: From CFR 2.1057 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 the equipment of WCDMA band II, this equates to a frequency range of 9 KHz to 20GHz, data taken from 30 MHz to 20 GHz.For WCDMA Band V, data taken from 30 MHz to 10 GHz. 2. The sweep time is set automatically by instrument itself. That should be the optimal sweep time for the span and the RBW. If the sweep time is too short, that is sweep is too fast, the sweep result is not accurate; if the sweep time is too long, that is sweep is too low, some frequency components may be lost. The instrument will give an optimal sweep time according the selected span and RBW. 3. The procedure to get the conducted spurious emission is as follows: The trace mode is set to MaxHold to get the highest signal at each frequency; Wait 25 seconds; Get the result. 4. Determine EUT transmit frequencies: below outlines the band edge frequencies pertinent to conducted emissions testing. TEST CONFIGURATION TEST PROCEDURE 1. The EUT was set up for the max output power with pseudo random data modulation; 2. The power was measured with Spectrum Analyzer N9020A; 3. These measurements were done at 3 frequencies for WCDMA band II/V. (low, middle and high of operational frequency range). TEST LIMIT Part 24.238, Part 22.917 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.

SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD. FCC ID: SS4SF550 Report No.: LCS1512161386E-02 4.7 Peak-to-Average Ratio (PAR) LIMIT The Peak-to-Average Ratio (PAR) of the transmission may not exceed 13 dB. TEST CONFIGURATION TEST PROCEDURE 1. Refer to instrument’s analyzer instruction manual for details on how to use the power statistics/CCDF function; 2. Set resolution/measurement bandwidth ≥ signal’s occupied bandwidth; 3. Set the number of counts to a value that stabilizes the measured CCDF curve; 4. Set the measurement interval as follows: 1). for continuous transmissions, set to 1 ms, 2). for burst transmissions, employ an external trigger that is synchronized with the EUT burst timing sequence, or use the internal burst trigger with a trigger level that allows the burst to stabilize and set the measurement interval to a time that is less than or equal to the burst duration. 5. Record the maximum PAPR level associated with a probability of 0.1%.
