手机测试都测试那些参数（Phone tests test those parameters） Phone tests test those parameters 2011-03-29:03-29, 03-29. The | classification: cell phone/communications | through 2033 Take GSM900 and 1800 for example 1. Test those parameters for calibration tests? What are the values of these parameters? Please attach the English abbreviation for Chinese. 2. What are the parameters for functional testing? What are the values of these parameters? Please attach the English abbreviation for Chinese. 3. What parameters are tested by coupling tests? What are the values of these parameters? Please attach the English abbreviation for Chinese. 4. In calibration test and functional test position, the computer, the synthesizer, the power supply, the fixture, GPIB card, GPIB wire, power cord, and rf wire are used. Is there anything else besides these? Can I use the COM port and the data acquisition card? If you cant use that, the probe on it is just power supply? 5. GSM900 and DCS 1800 are both digital cellular systems, but the frequency of work is different. Why should we use GSM and DCS to distinguish them? Please do not copy the long speech, I have checked a lot of information can not induce these questions, please answer my question. Thank you! No matter how much you know, please advise. To: The questioner adopted The main parameters of the test are: 1) launch power level TX power level (5 ~ 19) 2) frequency error frequency FER 3) Phase error Phase PER 4) RF Spectrum of RF Spectrum 5) switch spectrum SwitchSpectrum 6) Sensitivity RX Sensitivity 7) Modulation Spectrum Modulation Spectrum Main equipment needed for testing system: 1) the integrated tester of the simulated base station, such as the CMU200 of rod swartz, Germany 2) communication special power supply such as 2304A dual channel mobile communication high speed power supply, which is displayed when the pulse load changes He has significant voltage stability and can measure load current.
