主板MT6253,PA是RDA6232,使用MTK-ATE选择功率校准方式为GSM Full PCL,结果校准Pass。
选择功率校准方式是GSM RFMD,校准不通过,具体不通过log如下:
GSM PCL 16 = 10.73 PASS,Max :12.00 Min :10.00
GSM PCL 15 = 12.61 PASS,Max :13.80 Min :12.50
GSM PCL 14 = 14.67 PASS,Max :15.80 Min :14.50
GSM PCL 13 = 16.76 PASS,Max :17.80 Min :16.50
GSM PCL 12 = 19.00 PASS,Max :19.80 Min :18.50
GSM PCL 11 = 21.28 PASS,Max :21.80 Min :20.50
GSM PCL 10 = 23.57 PASS,Max :23.80 Min :22.50
GSM PCL 9 = 25.93 FAIL,Max :25.80 Min :24.50
GSM PCL 8 = 28.22 FAIL,Max :27.80 Min :26.50
GSM PCL 7 = 30.18 FAIL,Max :29.50 Min :28.50
GSM PCL 6 = 31.48 PASS,Max :31.60 Min :30.00
GSM PCL 5 = 32.19 PASS,Max :32.80 Min :31.70
怎么调试配置文件都不行,因为GSM RFMD校准速度快,适合于量产。
现在请教高人讲解下这两种校准方式区别,还有怎样才能选择GSM RFMD校准pass? |
