cfg文件问题
2,GSM900_2CAL_PCL = 12, 5,

请问上面这些参数是什么意思啊!每行的参数表示什么?
第一行,表示选取高中低 三个功率等级
第二行,不知道选取这两个功率等级 要干什么
第三行,表示GSM900的所有功率等级
第四行,表示要校准的所有功率等级
第五行~到第九行就不知道是什么了
求资深工程师指点

请问上面这些参数是什么意思啊!每行的参数表示什么?
第一行,表示选取高中低 三个功率等级
第二行,校准2个功率,rfmd不就是校准2个功率等级吗?
第三行,表示GSM900的所有功率等级
第四行,表示要校准的所有功率等级
第五行,校准功率最大上限范围(校准出来的值不能查过你的上限)
第六行,校准功率的期望值,期望值,就是你针对每个功率等级设置的标准
值,然校准时值就校准为上述值;
第七行,校准功率最小范围;
第八行,不是太清楚,但是一般不会去改动
第九行,调节线损用的,补偿(一般范围-2--+2)
随便写写,请不要笑话!
2楼大哥解释的很好!非常感谢~我还想问的是5,6,7行那些数值是测的什么的值,应该不是DAC的值吧!
解释得不错
5,GSM900_MAX_P = "8.0,9.5,11.0,12.5,14.5,16.5,18.5,20.5,22.5,24.5,26.5,28.5,30.5,31.5,33,"
校准结果的功率值最大上限范围(校准出来的值不能大过该上限值)
6,GSM900_WANTED_P = 6,7.5,9,11,13,15,17,19,20.8,22.7,25,27,29,30.5,32,
校准功率的期望值,也就是你针对每个功率等级设置的目标
值,校准时就以上述值为目标进行校准
7,GSM900_MIN_P = "4.0,5.5,7.0,9.5,11.5,13.5,15.5,17.5,19.5,21.5,23.5,25.5,27.5,29.5,31,"
校准结果的功率值最小下限范围(校准出来的值不能小过该下限值)
8,GSM900_C = 3,3,3,3,4,4,6,6,8,8,12,12,15,15,35,40,
对应各个功率等级的校准步进值,也就是达不到目标值时DAC值会先按该值进行加减
9,GSM900_CORRECTION = "0.1,0.3,0.4,0.4,0.3,0.1,0.1,0,0,0,0,0,0,0,0.1,"
对应各个功率等级的校准修正值,也就是校准的结果与目标值有差异时通过该值进行修正,使校准的结果接近目标值
学习学习!
不错 呵呵
8,GSM900_C = 3,3,3,3,4,4,6,6,8,8,12,12,15,15,35,40,
对应各个功率等级的校准步进值,也就是达不到目标值时DAC值会先按该值进行加减
这个步进值会自动增加到范围内,还是只增加或者减少一次,
