用8960校准时,SETUP文件里的线损是怎么对应设置的,比如下面:
AG8960_RF_Amptd_Freq_Offset Line0001 = "500000000,641000000,641100000,876000000,876100000,1312000000,1312100000,18800000"
AG8960_RF_Amptd_Freq_Offset Line0002 = "00,1881000000,1882000000,1883000000,1884000000,1885000000,2000000000,-1,-1,-1,-1"
AG8960_RF_Amptd_Freq_Offset Line0003 = ",-1,-1,"
AG8960_RF_Amptd_Value_Offset Line0001 = "-0.8,-0.8,-0.8,-0.8,-0.8,-0.8,-0.8,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,"
AG8960_RF_Amptd_Value_Offset Line0002 = "-1.0,-1.0,-1.0,-1.0
上面这些是怎么跟各个频段高\中\底信道对应的拉:
GSM 850: 128 190 251
GSM 900: 975 62 124
DCS1800: 512 698 885
PCS 1900:512 661 810
上面分别对应
AG8960_RF_Amptd_Freq_Offset里的那些频点,
如:500000000,641000000,641100000,876000000 这些是怎么算成对应的频段和信道,
希望各位帮我解决下这个问题,谢谢了。 |
