MTK-ATE自动校准过程说明AFC.docx

MTK-ATE自动校准过程说明之GSM-AFC由锁相环的原理知道，在锁相环锁定以后RF VCO的输出频率：Fvco26M/N ，即RFVCO的频率稳定度和频率精度由26MHz晶体振荡器的频率精度决定，所以校准射频频率合成器的频率精度就等于是校准26MHz晶体振荡器的频率精度。GSM规范要求手机的发射和接收信道频率精确度要在0.1ppm之内，手机通过接收基站的频率校准信道的信息，然后通过AFC去控制射频的VCTCXO可以将射频的频率误差控制在0.1ppm之内。可是每个TCXO之间存在着硬件偏差，所以需要校准。AFC校准参数：Initial DAC value; Slope;p AFC 初始DAC值 Initial value ，该值的范围从08191，对应AFC控制电压02.8V，校准完以后该值应该对应常温频率误差等于0的值，如三星TCXO校准完以后Initial value 为4750p 压控灵敏度slope，AFC slope 为单位DAC值能改变的射频频率误差，比如三星TCXO slope为2.7代表AFC DAC值每增加/减少1，对应的射频频率将增加/减少2.7Hz，手机通过比较本身产生的射频频率跟基站广播信道频率的误差计算出应该增加或者减少的AFC DAC值，从而保持跟基站频率同步，跟基站的频率误差控制在0.1ppm之内。1、 CAP ID校准1.1 CAP ID是电容值，是指的Crystal的负载电容。简单理解为一个LC震荡电路，而其中的C包含Crystal的内部负载带内容，与变容二极管的并联模式。CAP ID作用应该是通过改变不同的接入电容阵列值以适应不同的晶体，因此理论上它应该没有最优值，考虑到同款晶体也存在不一致性。1.2 AFC校准过程以下是引用heyunlong在2009-3-13 13:08:39的发言：由于GSM手机采用时分多址(TDMA)技术,以不同的时间段即时隙,来区分用户,故手机与系统保持时间同步就显得非常重要。若手机时钟与系统时钟不同步,则会导致手机不能与系统进行正常的通信。在GSM系统中,有一个公共的广播控制信道(BCCH),它包含频率校正信息与同步信息等。手机一开机,就会在逻辑电路的控制下扫描这个信道,从中获取同步与频率校正信息，如手机系统检测到手机的时钟与系统不同步,手机逻辑电路就会调整振荡电路的控制电压。其改变13/26MHz振荡电路中VCO两端的反偏压,从而使该VCO电路的输出频率发生变化,进而保证手机与系统同步。而手机的AFC（Auto Frequency Control自动频率控制）校准分两类型：一类型为Crystal，一类型为VC-TCXO。一类型为Crystal Crystal是指晶体Crystal AFC的校准过程；.先校准CAP ID在AFC DAC不变的前提下，在063（127）范围内之间选取一个CAP ID，选取的标准是其对应的发送信号频率频偏最小，然后对这个CAP ID进行验证是否在正确的范围中，针对6225平台而言，这个capid一般在3045之间。这个CAP ID对应的是TC里面的开关电容然后就是校AFC SLOPAFC DAC取3800（3900）4200（4300），得两个频偏值，再以这两组值算slope，之后就是验证，根据slope值算出频偏在0得那个DAC值，写进去再测试一下，确实是0左右，就说明校准成功了。一般AFC校不过，主要查查TRS有没有问题。再进行TX AFC offset 校准（这里有点不太清楚请高手指点。）AFC 主要是为了保证 Target 的时钟频率和网络正确同步。我们知道 DAC(数 模转换器)和 Frequency Offset(时钟频率偏移)有近似线性的关系，DAC-Frequency Offset 曲线由两个要素决定，一个是基准值(nominal value)， 一个是曲线的斜率(slope)。所谓的基准值指的就是当 Frequency Offset 值为零时 DAC 的值，如果还知道 Slope 的值，就可以根据任何一个 Frequency Offset 计算出对应的 DAC 值了。这个和DAC没有关系，校准这个的目的是为了补偿发射时PA对TXVCO或者LO的VCO PULLING作用所带来的些许频差。.一类型为TCVCXO (温度补偿压控晶体振荡电路)DAC值与TCVCXO输出频率（13/26MHz）之间的对应关系，使得测试接收信号的频率误差在允许范围之内。校准步骤：1.控制综测仪Agilent 8960或者 R&S CMU200设定在BCCH（广播控制通道）中的某一个通道arfcn_C0_GSM 可以为1-124中的一个，由板测软件初始设定），并设定发射功率为PDL（dBm）（由板测软件初始设定）；2.设定手机中频部分的接收增益为：-35-PDL（dB），AFC_DAC值为DAC1（由板测软件初始设定），软件发出AFC测试请求，在arfcn_C0_GSM通道上得到N_AFC个采样值；3.等待CPU计算出接收I/Q信号的频率平均误差：f1；4.再设定手机中频部分的接收增益为：-35-PDL（dB），AFC_DAC值为DAC2（由板测软件初始设定），这里DAC2DAC1，软件发出AFC测试请求，在测量通道上的到N_AFC个采样值；5.等待CPU计算出接收I/Q信号的频率平均误差：f2；6.计算AFC DAC斜率为：Slope=（f1-f2）/（DAC2-DAC1）; 由得到的Slope值及DAC1再计算得到初始ADC值：INIT_AFC_DAC为： Use Default Value=f1/ Slope+DAC1;判断该项板测结果是否通过，即看得到测量结果值：Slope、INIT_AFC_DAC是否在上下限值之内.然后将结果写入NVRAM区.MTK平台校准测试中TVCCXO AFC和Crystal AFC的异同点TVCCXO AFCAFC自动频率控制, 现在用的VC-TCXO 13/26M, 通信过程中目的是实时调整VC-TCXO 频率,使手机和基站频率保持一致,比如0.1PPM.手机收发的频率基准都是VC-TCXO,所以目的也是VC-TCXO频偏U601-SAW-U602路径）存在的不良，如断路、器件虚焊、器件不良、及中频内 部的频率解调电路存在的不良等；4.CPU在RF接收部分存在的不良；CAP ID校准过程：2014/05/21 09:22:13.656 - GSM CAP ID start -2014/05/21 09:22:13.656 CGsmCapIdClass:ParseCalibrationConfig()2014/05/21 09:22:13.656
