如何用CMU200測(cè)試CDMA_靈敏度解讀

1、如何讓用CMU200測(cè)試CDMA靈敏度首先設(shè)置CMU到CDMA頻段,GSM1800ModulationCrcurtSwitchedSingleSlotHIMenuSelectConnectControl進(jìn)入到CMDA測(cè)試界面，設(shè)置1stServiceclass為L(zhǎng)oopBackService(Test),截圖如下:CDMA2000CelarReceiverQualityRC1/1O-QPSKSO02接著到BSSignal，設(shè)置下參數(shù):RC 1/1O-QPSKSO 01ConnectControlCDMA2000Ce£arOverview修改RFChannel283為384,CDMAP
