Enter into META Mode OK
CAP ID[0]:0,DAC:4000,Freq:22.48(PPM[/COLOR]),Center Freq:894.00,Tch:20 这一项是什么意思呀?
CAP ID[1]:63,DAC:4000,Freq:-19.65(PPM[/COLOR]),Center Freq:894.00,Tch:20
Crystal CAPID check begin
CAPID=26,AFC DAC=0,FreqErr=-23147.2
PASS: Freq error PPM =-25.9
CAPID=26,AFC DAC=8000,FreqErr=18334.8
PASS: Freq error PPM =20.5
result[0]:-25.9
result[1]:20.5
AFC Calibration OK
Slope=6.363,min:1.000,max:10.000
Use Default Value=4004
============GSM900 Band=============
First AFC Tracking:i_DAC1 4004
DAC1:4004,gain:25,Frequency offset:-8 是什么意思呀?
Write the min tx afc offset 4 to NVRAM
FreqErr_min:9.25,tx_afc_offset_min 4
============DCS1800 Band=============
DAC1:4003,gain:25,Frequency offset:69
Write the min tx afc offset 3 to NVRAM
FreqErr_min:6.04,tx_afc_offset_min 3
================== TX AFC offset calibration end =====================
AFC Calibration time=16.28(sec)
TX AFC是怎么样计算出来的呀?是什么原理?和接收AFC是一样的吗?
急需高手刺教!先在此谢谢各位了! |
