请教一下大家两个问题:
1、在这个文件里改这个参数对不对。
2、可不可以不通过软件了来进行调整。
谢谢大家的帮助!
GSM850_CAL_PCL = 17, 12, 5
GSM900_CAL_PCL = 17, 12, 5
是不是功率校准的选点?如果是将17改为19。
19功率级下线的话就只能拿软件调整射频参数来改,应该不是电路的问题。注意Ramp曲线在19功率级的状态,有时不是功率问题,是曲线问题。
还有问问小编你用的是什么平台?下次提问的时候最好说一下
GSM900_MIN_P = 4,6,8,10,12.5,14.5,16.5,18.5,20.5,22.5,24.5,26.5,28.5,30,31.7
GSM900_C = 3,3,3,3,4,4,6,6,8,8,12,12,15,15,35,40
GSM900_CORRECTION = -0.3,0,0.2,0.3,0.4,0.2,0.1,0,0,0,0,0,0,0,0,
是什么意思?
这个要搞明白
同意二楼的说话,这个和平台的关系很大。
不同平台的设置不一样的。
你应该找下 high weight、Low weight修改。
个人觉得,Low weight设置下 应该就好了,
MTK平台的。
等我回去验证一下大家的建议。
谢谢!
请问一下 high weight、Low weight的high、low指的是什么意思?功率平坦度是不是也可以用他来调整?
谢谢!
看大家的意思,看来MTK和agere的平台一样,并不是所有的level都
做cal,而是选择一个level来作。在选定的那几个level和cal ch,pwr基本事非常准确的。
但是其他的level就是用window来拟合了。
heigh weight合low weight看来事加权因子了,用来补偿拟合的不准确性。
修改high weight、Low weight可以搞定。3Q!
