Base Station Spectrum Analyzer EUT According with KDB 971168 v02r02 5.7.2 Alternate procedure for PAPR 5.1.2 Peak power measurements with a peak power meter a) The total peak output power may be measured using a broadband peak RF power meter. The power meter must have a video bandwidth that is greater than or equal to the emission bandwidth and utilize a fast-responding diode detector. 5.2.3 Average power measurement with average power meter As an alternative to the use of a spectrum/signal analyzer or EMI receiver to perform a measurement of the total in-band average output power, a wideband RF average power meter with a thermocouple detector or equivalent can be used under certain conditions If the EUT can be configured to transmit continuously (i.e., the burst duty cycle 98%) and at all times the EUT is transmitting at is maximum output Test Report 18070321-FCC-R1 Page No. 16 of 55 power level, then a conventional wide-band RF power meter can be used. If the EUT cannot be configured to transmit continuously (i.e., the burst duty cycle < 98%), then there are two options for the use of an average power meter. First, a gated average power meter can be used to perform the measurement if the gating parameters can be adjusted such that the power is measured only over active transmission bursts at maximum output power levels. A conventional average power meter can also be used if the measured burst duty cycle is constant (i.e., duty cycle variations are less than 2 percent) by performing the measurement over the on/off burst cycles and then correcting (increasing) the measured level by a factor equal to 10log(1/duty cycle) Remark Result Pass Fail Test Data Yes N/A Test Plot Yes (See below) N/A Test Report 18070321-FCC-R1 Page No. 17 of 55 GSMGSM 1900 PK-AV POWER (PART 24E) Frequency Conducted power(dBm)

1, The testing has been conformed to 10*1909.8MHz=19,098MHz 2, All other emissions more than 30 dB below the limit 3,GSM voice and GPRS mode were investigated. The results above show only the worse cases 4, X-Axis, Y-Axis and Z-Axis were investigated. The results above show only the worst case. 5, The radiated spurious test above 18GHz is subcontracted to SIEMIC (Nanjing-China) Laboratories. and found 30dB below the limit at least. 6.7 Band Edge Temperature Relative Humidity Atmospheric Pressure Test date :

Test setup Procedure Remark Base Station Spectrum Analyzer EUT

- The EUT was connected to Spectrum Analyzer and Base Station via power divider.

- The Band Edges of low and high channels for the highest RF powers were measured. Setting RBW as roughly BW/100. Result Pass Fail Test Data Yes N/A Test Plot Yes (See below) N/A Test Report 18070321-FCC-R1 Page No. 32 of 55 GSM Voice:
