To ensure the quality and performance of the mobile phone, we need to tune those parameters of mobile phone components by a special application tool. CFT (Calibration & Final Test) is used to do RF tuning and calibration automatically so that making the mobile precisely working and conforming to the 3GPP specifications. In addition, some mobile phones cannot normally work due to the production technology deviations. CFT can also distinguish those issue phones to make sure the quality of mass production.CFT supports:l Battery calibration (ADC).l RF parameter tuning (AFC/APC/AGC)l RF performance test (Final Test according to 3GPP specification)l Current Test (Power Off / Deep Sleep)1.2 Runtime environment1.2.1 Hardwaren Generic Pentium III PC or above.n Agilent 8960 or R&S CMU 200 or Anritsu MT8820C, CMWCMU 200 suggests software V5.20 above.Agilent 8960 suggests E1969A.n NI or Agilent GPIB device (NI GPIB is highly recommended)n Agilent 663XX or Keithley K230X series power supply (Agilent66319D, Keithley K2304 is highly recommended)1.2.2 Softwaren Microsoft Windows 2000 or XP, Vista, Win7.

System role selectionThere are three system roles supported:n CFT: Calibration and then Final Test.n FT (Final Test): Final Test Only.n Antenna Test: Antenna Test. Antenna Test is almost same with FT mode, only the test specification is larger than FT because during Antenna Test, DUT connects with instruments by antenna directly, not RF cable.l 2. Select the test project. If you have no idea about the selection of projects, please contact with SPRD FAE. Open configuration file of each project.l 3. Tuning and calibration items, including ADC, AFC, AGC, and APCl 4. Final test selection, Make Call and Final Test item selection Click button to configure options of HandOver feature.l 5. Misc. test item such as read SW version, Current Test Click button to select items of current test, current specification Click button to select another items.l 6. Advance settingClick Advance Setting button, the advance setting interface as shown as below.Figure 3-2 Advance settings interface1. Advance control settings:Stop if failed x times during final testing:It allows to stop testing when the system failed x times during final testing. Phone Notify to Start Test automatically: When CFT detects mobile phone is connected, CFT start to test automatically. (Recommend)Calibration pos X mode (Shut-down LCM):Final testing is tested in calibration post X mode which mode that LCM would be shut-down.Please contact with SPRD FAE to make sure that whether the S/W supports X mode or not.Shut down power supply after finish testing:After test is done, CFT would shut down power supply automatically. (Recommend)Repeat testing x times:Repeat testing for laboratory.2. Log system settings:Enable Instruments Gpib Log:Log GPIB command to a file, file name is Gpib.txt. PhoneCommand Log:Log the mobile phone and PC communication command to a file, file name is ComX_UsefulLog.txtEnable Arm Log & Save Arm Log To Local File:Enable Arm Log of mobile phone during testing, and save the captured log to a file.Save Dsp Log To Local File:Save DSP log to a file.
